Accomplishments

<p><strong><span style="text-decoration: underline;">California:</span></strong> Rob Wilson, California Rocky Mountain Research and Extension Center, completed two cultural management studies in 2015 that included entries from the Western Regional program.&nbsp; One management study evaluated black spot and white knot bruising on Russet entries in storage.&nbsp; The other management study evaluated the appearance and quality of red and yellow skin specialty varieties after storage and commercial polishing</p><br /> <p><strong><span style="text-decoration: underline;">Colorado:</span></strong> Colorado grew 86,349 first-year seedlings representing 456 families in 2015, with 742 selected for subsequent planting, evaluation, and increase in future years.&nbsp; A portion of these seedlings were obtained from the USDA-ARS (Aberdeen, Idaho), Agriculture Canada, Texas A&amp;M University, North Dakota State University, and the University of Maine.&nbsp; Another 865 clones were in 12-hill, preliminary, and intermediate stages of selection.&nbsp; At harvest, 242 were saved for further increase and evaluation in 2016.&nbsp; Sixty-two advanced selections were saved and will be increased in 2016 pending further evaluation.&nbsp; Another 271 selections and cultivars were maintained for germplasm development, breeding, and other experimental purposes including seed increase/maintenance.</p><br /> <p><strong><span style="text-decoration: underline;">Idaho:</span></strong> Four new russet varieties were released in 2015 from the cooperative USDA/ARS - University of Idaho potato breeding and variety development programs in Aberdeen, Idaho.&nbsp; The releases were made jointly by the USDA/ARS and the experiment stations of Idaho, Washington, and Oregon. The four new varieties include Targhee Russet (A01010-1), Payette Russet (A02507-2LB), Mountain Gem Russet (A03158-2TE) and Pomerelle Russet (A02062-1TE).</p><br /> <p><strong>Targhee Russet</strong> is a dual purpose variety with vine maturity similar to Russet Burbank. It produces a high yield of attractive, long tubers with brown-russeted skin.&nbsp; It has been trialed in both the western and eastern U.S. with higher marketable yields and fresh merit evaluation scores noted at most trial sites relative to Russet Burbank. However, tuber dormancy is about 50-60 days shorter than Russet Burbank. It is notable for its resistance to soft rot and has excellent resistance to most internal and external defects including blackspot bruise and hollow heart. It has significantly higher protein and vitamin C contents than those of most standard varieties, indicating that it can provide enhanced dietary levels of these phytonutrients.&nbsp; Targhee Russet has moderate specific gravity and produces lighter colored fries out of storage than standard processing varieties. Industry evaluations of processing quality also indicate that Targhee Russet has good potential for producing fresh-cut fries.</p><br /> <p><strong>Payette Russet</strong> is a full-season processing variety with higher yields of oblong, medium-russeted tubers having higher protein content than those of the standard russet potato varieties.&nbsp; It has excellent cold-sweetening resistance, resulting in significantly lower reducing sugar concentrations and lighter fry color out of long-term storage than Russet Burbank and Ranger Russet. Tuber dormancy for Payette Russet is about 30 days shorter than Russet Burbank but it can be stored at 42^oF, which significantly extends the dormancy period.&nbsp; Emergence is later than Russet Burbank, so Payette Russet needs at least a 120 day growing season for efficient production. It has resistance to tuber malformations and most internal and external defects, including blackspot bruise and hollow heart.&nbsp; It has foliar and tuber resistance to late blight, as well as resistance to Verticillium wilt, early blight, and common scab. However, it is susceptible to Fusarium dry rot and will need to be managed accordingly. Payette Russet is also notable for having a high level of resistance to all PVY strains due to incorporation of the&nbsp;<em>Ry_sto&nbsp;</em>gene.</p><br /> <p><strong>Mountain Gem Russet</strong> is a medium to late maturing variety notable for its high yields in both early and full-season trials. &nbsp;Tubers of Mountain Gem Russet are oblong-long, medium-russeted with higher protein content than those of standard potato varieties. Sensory evaluations by taste panels have shown this variety to have excellent culinary qualities.&nbsp;&nbsp;&nbsp; It has greater resistance to tuber late blight, tuber malformations and most internal and external defects than Russet Burbank. Mountain Gem Russet maintains acceptable reducing sugar concentrations and fry quality when stored at 48^oF and shows good potential for early processing. Tuber dormancy is about 70 days shorter than Russet Burbank. <em>Fusarium</em> dry rot susceptibility and weight loss in storage are similar to Russet Burbank. Mountain Gem Russet&rsquo;s high early and late season total and U.S. No. 1 yields, coupled with good culinary and nutritional qualities, make it an excellent candidate for fresh market production.</p><br /> <p><strong>Pomerelle Russet</strong> is an early maturing fresh variety, which produces moderately high early-season yields of long tubers with brown-russeted skin. It is notable for its very attractive, smooth skin and resistances to internal and external defects with a high percentage of U.S. No. 1 yield. Relative to industry standard varieties Russet Burbank and Russet Norkotah, Pomerelle Russet has greater resistance to soft rot, corky ringspot and tuber infections from late blight. It also has much lower total glycoalkaloid concentrations and higher protein and vitamin C concentrations than Ranger Russet and Russet Burbank. It has moderate specific gravity and good resistance to sugar ends. It also has moderately long tuber dormancy, about 30 days shorter than Russet Burbank, and can maintain acceptable fry color for about 180-200 days in storage at 48^oF, indicating some potential for processing out of short or mid-term storage. However, its primary use appears to be as a high quality, early fresh variety.</p><br /> <p>In 2015, potato breeding clones, including over 100,000 single hills (1^st field generation clones), were planted, maintained, and harvested at three seed sites, with advanced breeding clones being evaluated in 32 replicated field trials in six locations across southern Idaho for their potential as new potato varieties. Particular emphasis was placed on selecting breeding clones with adaptation to local conditions, dual utility with use in both fresh and processing markets, production efficiency, and multiple disease resistances.</p><br /> <p><strong><span style="text-decoration: underline;">Oregon:</span></strong> Molecular techniques have been refined, which should hasten the transfer of desirable genes among varieties and introgression of novel genes from related wild species.&nbsp; Recent collaborations with USDA/ARS faculty at Aberdeen, ID resulted in the combination of PVY, PVX, and pale cyst nematode resistance in a single cross using molecular markers.&nbsp; OSU has recently validated the use of similar markers to screen for resistance to Columbia root-knot nematode (CRKN) and late blight Rb genes.&nbsp; An effort to develop &ldquo;Russet-All&rdquo; association mapping panel was initiated in collaboration with other U.S. breeding programs.&nbsp; Two hundred and sixty-four russet clones were collected and fingerprinted using 24 simple-sequence repeat markers. Genetic diversity analysis on these clones is underway to identify different heterotic groups. A subset of these clones in different heterotic groups, along with wild germplasm and long-day adapted <em>S. phureja &ndash; S. stenotomum </em>populations will be used for future studies on heterosis, marker-trait associations and genome wide selections. Further, whole genome sequence resources are being developed for <em>S. bulbocastanum</em>. We have assembled a draft genome of diploid <em>S. bulbocastanum</em> SB22 to provide additional genomic resources relevant to potato breeding. The reference genome of tetraploid <em>S. tuberosum</em> was used as a starting point for the assembly. The current genome assembly consists of 87,828 contigs ranging in length from 1,000 bp to 209,398 bp with total assembly of over 441mb.</p><br /> <p>&nbsp;</p><br /> <p><strong><span style="text-decoration: underline;">Texas:</span></strong> 79,312 first year seedlings, resulting from 493 different parental combination or families (crosses), were grown for selection on the Barrett Farm (37,231) near Springlake and on the CSS Farm (42,081) near Dalhart</p><br /> <p><strong><span style="text-decoration: underline;">&nbsp;</span></strong></p><br /> <p><strong><span style="text-decoration: underline;">Washington:</span></strong> The effect of the Tri-State Potato Variety Development Program on the Northwest potato industry has been substantial. <strong>Ranger Russet, Umatilla Russet, Alturas, Bannock Russet, and Clearwater Russet</strong>, are examples of russet cultivars released from the Tri-State program that have greatly benefited the United States and Northwest potato industry, being the 3nd, 4th, 7th, 8th, and 16th most widely grown cultivars in the United States in 2015, respectively, with Tri-State varieties representing 23%, or 220,000 acres, of the fall crop nationally.

Western Regional Russet Early/Late Results – Rich Novy

• Reviewed: 2016 Western Regional Potato Variety Trial Report; compiled by Brian Schneider (USDA-ARS). Report can be found at ars.usda.gov/main/docs.htm?docid=21888


• Tom Salaiz (McCain) asked a question about statistics; there were no differences statistically on early yield results


• Tom Salaiz (McCain) asked how sugar ends are rated. Rich Novy (USDA-ARS) said each location has their own system. Rich Novy said Aberdeen rates harder than industry. Chelsey Lowder (UI) said they use visual. Douglas Scheuring (TAMU) said they use visual. Sagar Sathuvalli (OSU) said they use stem end difference; more than 15 photovolt difference. Rich Novy (USDA-ARS) asked Tom Salaiz (McCain) if there was a different way he would like that done, Tom said no.


• Creighton Miller (TAMU) made a clarification that entry #15 is yellow flesh russet with red eyes.


• Jonathan Whitworth (USDA-ARS) reviewed results from disease table #12

Accomplishments

<p><strong><span style="text-decoration: underline;">California:</span></strong> Rob Wilson, Intermountain Research and Extension Center, completed a cultural management study in 2016 that included graduated entries from the Western Regional program.&nbsp; The management study evaluated black spot and white knot bruising on Russet entries in storage.&nbsp;</p><br /> <p><strong><span style="text-decoration: underline;">Colorado:</span></strong> Colorado grew 86,244 first-year seedlings representing 520 families in 2016, with 419 selected for subsequent planting, evaluation, and increase in future years.&nbsp; A portion of these seedlings were obtained from the USDA-ARS (Aberdeen, Idaho), Agriculture Canada, Texas A&amp;M University, North Dakota State University, and the University of Maine.&nbsp; Another 907 clones were in 12-hill, preliminary, and intermediate stages of selection.&nbsp; At harvest, 289 were saved for further increase and evaluation in 2016.&nbsp; Sixty-six advanced selections were saved and will be increased in 2017 pending further evaluation.&nbsp; Another 284 selections and cultivars were maintained for germplasm development, breeding, and other experimental purposes including seed increase/maintenance.</p><br /> <p><strong><span style="text-decoration: underline;">Idaho:</span></strong> In 2016, potato breeding clones, including 99,400 single hills (1^st field generation clones), were planted, maintained, and harvested at three seed sites, with advanced breeding clones evaluated in 32 replicated field trials in six locations across southern Idaho for their potential as new potato varieties. Particular emphasis was placed on selecting breeding clones with adaptation to local conditions, dual utility with use in both fresh and processing markets, production efficiency, and multiple disease resistances. Twenty-two entries from the Aberdeen program were entered in advanced agronomic and processing trials in the Tri-State and Western Regional to assess their performance relative to industry standards.</p><br /> <p>In addition, the breeding program is progressing in developing germplasm with genetic resistance to PVY, PVX, and PLRV, PMTV, late blight (foliar and tuber), nematodes, corky ringspot and zebra chip disease, for example entries A08422-2VRsto and A08433-4VR both exhibit extreme resistance to PVY. Additional studies were conducted in 2016 designed to compare nitrogen and phosphorus use efficiency of 6 new varieties or advanced clones from the breeding program with that of Russet Burbank. All had significantly higher N and P use efficiency than Russet Burbank.</p><br /> <p>Also in 2016, two varieties released by the Tri-State Potato Variety Development Program, Blazer Russet and Clearwater Russet, were accepted by McDonald&rsquo;s for French fry production. As a result, four of the seven potato varieties currently accepted by McDonald&rsquo;s for French fry production in North America were developed by the Tri-State program.</p><br /> <p><strong><span style="text-decoration: underline;">Oregon:</span></strong> Tri-State varieties continue to perform well in various production regions throughout the USA and abroad. Breeding efforts at OSU complement and enhance those of the USDA/ARS programs in Aberdeen, ID and Prosser, WA by incorporating disease and pest resistances using multi-trait genotypic recurrent selection.&nbsp; Molecular techniques have been refined, which should hasten the transfer of desirable genes among varieties and introgression of novel genes from related wild species.&nbsp; Recent collaborations with USDA/ARS faculty at Aberdeen, ID resulted in the combination of PVY, PVX, and pale cyst nematode resistance in a single cross using molecular markers.&nbsp; OSU has recently validated the use of similar markers to screen for resistance to Columbia root-knot nematode (CRKN) and late blight Rb genes.&nbsp; We are developing new molecular markers linked to resistance to CRKN and also identifying new sources of resistance to roza pathotype of CRKN and Verticillium wilt. Further, we fingerprinted all the varieties handled by PVMI using SSR markers and SNP markers and the data is available for the public at PVMI.org.</p><br /> <p><strong><span style="text-decoration: underline;">Texas:</span></strong> 73,043 first year seedlings, resulting from 463 different parental combination or families (crosses), were grown for selection on the Barrett Farm (33,161) near Springlake and on the CSS Farm (41,659) near Dalhart. Virtually all of the russet potatoes grown in Texas in 2016 were the improved Texas Russet Norkotah strains.&nbsp; Over the past several years, Texas recorded the highest summer crop yields in the nation (ranging from 440-465 Cwt/A) among some 9 states producing a summer crop.&nbsp; In 2016, the four Texas Russet Norkotah selections (TXNS112, TXNS223, TXNS278, and TXNS296) collectively ranked in the third position among the top 50 US varieties in acres accepted for seed certification. The varieties ranking above these four selections were released years earlier. Reveille Russet, released in 2015, is gaining rapid acceptance, with demand far exceeding seed supply.</p><br /> <p><strong><span style="text-decoration: underline;">Washington:</span></strong> The effect of the Tri-State Potato Variety Development Program on the Northwest potato industry has been substantial. <strong>Ranger Russet, Umatilla Russet, Alturas, Bannock Russet, and Clearwater Russet</strong>, are examples of russet cultivars released from the Tri-State program that have greatly benefited the United States and Northwest potato industry, being the 3rd, 4th, 7th, 9th, and 10th most widely grown cultivars in the United States in 2016, respectively, with Tri-State varieties representing 33.5%, or 309,000 acres, of the fall crop nationally. (NASS, Crop Production, December, 2016). <strong>Ranger Russet, Umatilla Russet, and Alturas</strong> were the 3^rd, 4^th, and 5^th most widely grown cultivars in the PNW (ID, OR, WA) in 2016, respectively, and accounted for 27% of the PNW planted acreage.&nbsp; Varieties recently released by the Tri-State program are now produced on more than 143,000 acres in the Pacific Northwest with value to growers estimated at approximately $600 million.&nbsp; In the past 10 years, the US farm-gate value of Tri-State varieties has increased by approximately $190 million.</p><br /> <p>Produced detailed growth, development and storability profiles for newly released cultivars (NWVDP) under four levels of in-season N (ranging from deficit to excess), modeled the attainment of tuber physiological maturity and determined subsequent effects of the N levels on retention of nutritional and process qualities during storage.</p><br /> <p>Screened cultivars/clones for tolerance to high temperature imposed during tuberization, bulking and maturation on postharvest physiology, storability and quality as process and seed potatoes (e.g. Sage Russet, Clearwater, Ranger, A02138-2, POR06V12-3, A02507-2LB).</p><br /> <p>Evaluated the effects of P nutrition on retention of process quality (Ranger Russet, Russet Burbank, Umatilla Russet, Alpine Russet, Sage Russet, Teton Russet, Alturas).</p><br /> <p>Determined the effects of water stress imposed at critical periods of tuber development on productivity, water use efficiency, crop value, postharvest physiology and retention of process quality (Teton Russet, Alturas, Targhee Russet, Classic Russet, Clearwater Russet, GemStar Russet, Ranger Russet, Russet Burbank, Umatilla Russet).</p><br /> <p>Screened advanced LTS-resistant clones from the Northwest Variety Development Program for tolerance to in-season and postharvest heat stress for retention of LTS-resistant phenotype.

AGENDA

A motion to approve the agenda was brought up by Jeff Koym (Texas A&M); approved by unanimous vote.

MINUTES

A motion to approve the minutes was brought up by Jeanne Debons (PVMI); first by Jeff Koym (Texas A&M) and second by Chelsey Lowder (UofI); approved by unanimous vote.

Sagar Sathuvalli (OSU) requested chip color index measurements to remain consistent, using a scale of 1 – 5, instead of the 1 – 6 scale that was used on table 9 of the chip report.

Sagar Sathuvalli (OSU) proposed sequencing potato variety Atlantic at the University Wisconsin. The cost of sequencing will cost $120,000 and asked for the industry and other universities to help fund this project. He offered to help with $20,000 to fund this project.

Jeanne Debons (PVMI) announced a new feature offered within the PVMI website called “exclusive opportunities” for those who would like to “champion” varieties that have not been release but are available for commercial marketing.

Jeff Koym (Texas A&M) proposed developing a “verbal” classification to characterized the length-to-width ratio of potatoes.

California – Rob Wilson

• They have been working on organic amendments on specialty varieties.

Colorado – Dave

Idaho –

In 2017, potato breeding clones, including 118, 111 single hills (1st field generation clones), were planted, maintained, and harvested at three seed sites, with advanced breeding clones evaluated in 32 replicated field trials in six locations across southern Idaho for their potential as new potato varieties.

We had 5 russet clones in the Western Regional Trials.

In the Late Western Regional Trial at Aberdeen, the top yielding clones were A08433-4VR, A07061-6, and AOR06070-1KF all of which exceeded the standard cultivar yields.

Specific gravities for each of the top yielding clones were higher than Russet Burbank. The incidence of hollow heart for AOR06070-1KF (43%) is a potential concern since it averaged 40% hollow heart in 2015. C008065-2RU and C00823 l-1RU also had high percentages of hollow heart. All of the clones had relatively light fry colors after 3 months of storage at 45°F except for TX08352-5Ru. TX08352-5Ru, A08009-2TE, and A06030-23 had the highest merit scores.

There also were some very high yielding clones in the Late Western Regional Trial at Kimberly, including A07061-6, COTX09022-3RuRE/Y, A08433-4VR, and A03141-6 (Table 4). A07061- 6, A03141 -6 produced the highest US No. 1 yields, which were substantially higher than the standard cultivars. Specific gravities for the four highest yielding experimental clones were all higher than the standard varieties. Merit scores were highest for TX08352-5Ru, C00823 l-1RU, A006191-1, AOR06070-1KF, A06030-23, and C008065-2RU. All clones had acceptably light fry colors after 3 months of storage, except for A08009-2TE and TX08352-5Ru.

Texas – Dr. Creighton Miller

• Isabel Vales assumed leadership of the Texas Potato Breeding and Variety Development Program in January 2017. Isabel’s first year focused mainly on the conventional aspect of the breeding program in order to identify production constraints and define priorities and research direction for the Texas Program. Dr. Miller remains involved during the transition period.


• 56,014 first year seedlings, resulting from 369 different full-sib families, were grown for selection on the Barrett Farm (3,936) near Springlake and on the CSS Farm (52,078) near Dalhart. Around 360 original selections were made (0.6% selection intensity)


• We received seedlings tubers from the Idaho (7,097), Colorado (20,019), and North Dakota (8,563) breeding programs.


• We grew 15,966 tuberlings in the greenhouse at College Station from true seed and sent tuberlings to Idaho (1,154), Colorado (9,710), and North Dakota (5,810). We sent 2,000 true potato seed to Minnesota.


• Our crossing block 2016-17 was very successful. We had 62 parents with a 34% success rate which produced 183 families. Approximately 169,275 true seed was produced. We are very happy with the new greenhouse installations at HortTrec.


• Trials were conducted at Spring lake (summer crop– planted March 21-27 and harvested July 2, 4, 24, and 28 ) and Dalhart (fall crop– planted  May 15-19 and harvested  September 3,11 and 22) -  987 advanced selections/new cultivars were evaluated in 42 separate trials. This involved planting/harvesting over a six-month period.


• Southwestern and Western Regional Trials were conducted at both Springlake (Chip, Russet and Red/Specialty) and Dalhart (Chip, Russet and Red/Specialty).


• The Texas program entered three selections (COTX00104-6R, NDTX059759-3RY/Y Pinto, and PORTX03PG25-2R/R) in the Western Regional Red/ Specialty Trial, two selections in the Western Regional Russet Trial (COTX09022-3RuRE/Y and TX08352-5Ru) and one selection in the Western Regional Chip Trial (NDTX081648CB-13W). The program also entered two selections in the Southwest Regional Russet Trial (AOTX05043-1RU and COTX05095-2RU).


• The Texas Program had 16 entries (AORTX09032-3W, AORTX09033-4W, AORTX09037-1W, AORTX09037-4W/Y, AORTX10247-1W/Y, NDTX113030C-3W, AORTX09033-11W, AORTX09037-5W/Y, AORTX09144-2W, COTX12235-2W, COTX12428-1W, NDTX113467CB-1W, NDTX12203AB-1W, NDTX1244-3W/Y, NDTX1246-3W/Y, and TX13563-1W) in the Potatoes USA Fast-Track National Chip Processing Trial.


• One Texas entry (NDTX081648CB-13W) was included in the National Snack Food Trial.


• The Texas Potato Field Day was held on July 13, 2017 on the Barrett Farm near Springlake, and included some 70 attendees, ranging from Canada to Mexico. Vales was introduced to the industry.


• Zebra Chip evaluations were conducted based on artificial infestation under field and greenhouse conditions. Results showed promising tolerance in diploids, advanced clones with crop wild introgressions, and wild relatives.


• Emphasis on virus testing and clean-up continued. We purchased a new ELISA plate reader.


• Our lab is equipped for basic molecular biology work. We have purchased the necessary equipment and supplies.


• We have a master student (Sam Vigue), a PhD Student (Jeewan Pandey) and three undergraduate students.


• The Texas Russet Norkotah strains continue to be the prevalent varieties planted in Texas. Potato yields in Texas remain amongst the highest in the nation (440-465 cwt/a) among the summer crop producing states.


• The Texas Russet Norkotah selections (TXNS112, TXNS278, and TXNS296) collectively ranked third (in acreage) among the varieties accepted for seed certification in 2016. Russet Burbank and Frito varieties ranked above these three selections.


• Reveille Russet, released in 2015, is gaining rapid acceptance (17 licensees in 8 States), with demand far exceeding seed supply.

Accomplishments

<p><strong>Idaho</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Summary of accomplishments:</strong></p><br /> <p>Over 110,000 Aberdeen-generated seedling tubers and approximately 20,000 seedling tubers obtained from other state breeding program were planted on 28 acres for first field generation selection at Aberdeen, as well as an additional 1,800 second-field year (12-hill) selections. Seven agronomic trials of Aberdeen breeding clones and the National Fry Processing Trial were planted at Aberdeen and Kimberly, as well as disease screening trials for early blight, common scab, and PVY/PLRV.&nbsp; In addition, the Tri-State Specialty Trials were conducted at Parma and Aberdeen.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Tri-State and Western Regional Trial Results</strong></p><br /> <p>In 2018, 11 entries from the Aberdeen program were entered in advanced agronomic and processing trials in the Tri-State and Western Regional to assess their performance relative to industry standards. We had 5 russet clones in the Western Regional Trials, 6 russet clones in the early season Tri-State Variety Trials, and 5 in the late season Tri-State Variety Trials.</p><br /> <p><strong>Russet Trial Results: </strong>The highest yielding clones in the Aberdeen Early Tri-State Trial were A07705-4, AOR10204-3, A07098-4, OR12133-10, and A08510-1LB, all of which produced higher total and yields than the standard cultivars, and higher U.S. No. 1 yields than Russet Burbank and Russet Norkotah (Table 1). However, only AOR10204-3, A07098-4 produced higher U.S. No. 1 yields than Ranger Russet. Specific gravities for these clones were comparable to Ranger Russet, Russet Burbank and Russet Norkotah, with the exception of A07705-4 and AOR10204-3, which were relatively low. Merit scores were highest for A07098-4, A07705-4, AOR08540-1, and POR12NCK50-1. Hollow heart incidence was low for all clones.</p><br /> <p><strong>Table 1 Yield and quality characteristics of four standard russet potato cultivars and ten breeding lines grown in Early Tri-State

The efficiency of N fertilizer use for these new clones is substantially greater than standard varieties, ranging from 10-25% better than Russet Burbank. Reducing fertilizer applications per unit of yield produced would provide a considerable economic benefit to growers and would also contribute significantly to the sustainability of potato production systems. Additional studies were conducted to determine optimal phosphorus rates, seed management practices, seed piece spacing, and N management guidelines for new and previously released Tri-State varieties. The phosphorus requirements of most of the new varieties were similar to or lower than those for Russet Burbank and Ranger Russet.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Specialty Trial Results:</strong></p><br /> <p>Promising specialty breeding lines from the Pacific Northwest Potato Variety Development Program were evaluated in two locations. These same lines were also evaluated for dormancy length, and chemical composition.</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><em>Field Evaluations - </em>Seed of two standard potato cultivars and 3 breeding lines were obtained from Brian Charlton (OSU, Klamath Falls).&nbsp; This seed was used in replicated trials at both the Parma and Aberdeen R&amp;E Centers.&nbsp; The seed was cut, organized into a randomized, four-replicate trial, and planted at the Aberdeen and Parma R &amp; E Centers.</p><br /> <p>&nbsp;</p><br /> <p>Chieftain produced a total yield of 577 cwt/acre at Parma, while A08122-12R and POR14PG22-3 were the only breeding lines above 500 cwt/acre.&nbsp; (Table 5).&nbsp;&nbsp; These same lines were also among the highest yielding selections at Aberdeen (Table 6).&nbsp; Chieftain and Yukon Gold had a high proportion of tubers over 10 oz at Parma. In contrast, none of the varieties or breeding lines produced high yields of over 10 oz tubers at Aberdeen. Tubers above 10 oz are not generally desirable for the specialty market.&nbsp; The premium yield category (2-6oz) was added to capture the perceived optimum size of specialty tubers for fresh market.&nbsp; A08112-7R, A08122-12R and POR14PG22-3 all tended to produce high premium yields at both locations (Tables 5 and 6).</p><br /> <p>&nbsp;</p><br /> <p>Specific gravity ranged from 1.074 to 1.087 at Parma, and from 1.071 to 1.088 in Aberdeen (Tables 5 and 6).&nbsp; Yukon Gold had the highest specific gravity at both locations.&nbsp; Specific gravity greatly effects cooking quality, and this information should be used with the culinary evaluations reported in the WSU cultivar report to make decisions about appropriate uses for these new potential varieties.&nbsp;&nbsp;</p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>&nbsp;</strong></p><br /> <p><strong>Table 5 Yield and quality characteristics of two standard specialty potato cultivars and three breeding lines grown in Parma, ID during 2018. ¹</strong></p><br /> <p><strong>^&nbsp;</strong></p><br /> <table width="717"><br /> <tbody><br /> <tr><br /> <td rowspan="2"><br /> <p><strong>Cultivar/Breeding line</strong></p><br /> </td><br /> <td rowspan="2"><br /> <p><strong>Total Yield</strong></p><br /> </td><br /> <td rowspan="2"><br /> <p><strong>No. 1 Yield</strong></p><br /> </td><br /> <td rowspan="2"><br /> <p><strong>Premium Yield&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Brief Summary of Minutes

Accomplishments

<ul><br /> <li>The effect of the Tri-State Potato Variety Development Program on the Northwest potato industry has been substantial. Ranger Russet, Umatilla Russet, Clearwater Russet, Alturas, and Bannock Russet are examples of russet cultivars released from the Tri-State program that have greatly benefited the United States and Northwest potato industry, being the 3rd, 4th, 6th, 7th, and 12th most widely grown cultivars in the United States in 2018, respectively, with Tri-State varieties representing 31%, or 266,400 acres, of the fall crop nationally.</li><br /> <li>Ranger Russet, Umatilla Russet, and Clearwater Russet were the 3rd, 4th, and 5th most widely grown cultivars in the Pacific Northwest (ID, OR, WA) in 2018, respectively, and accounted for 25% of the planted acreage. Varieties recently released by the Tri-State program are now produced on more than 160,900 acres in the Pacific Northwest with value to growers estimated at approximately $810 million. In the past 16 years, the US farmgate value of Tri-State varieties has increased by approximately $240 million.</li><br /> <li>Acceptance of these varieties is supported by the agronomic information and postharvest testing conducted by the participants. Recommendations for cultivation and storage management are well developed before full release of each variety. Further, acceptability for processing is confirmed.</li><br /> <li>Colorado cultivars and clonal selections accounted for 36% of the 7,858 acres of Colorado certified seed accepted for certification in 2018. Advanced Colorado selections accounted for another 2% of the seed acreage.</li><br /> <li>Colorado State University releases accounted for 37% of the estimated 51,900 acres planted to fall potatoes in Colorado in 2017. Primary Colorado cultivars planted were Canela Russet (10.4%), Russet Norkotah-S8 (10.4%), Russet Norkotah-S3 (7.5%), Centennial Russet (4.3%), and Rio Grande Russet (4.2%).</li><br /> <li>Four of the top 20 russet cultivars grown for seed in the U.S. [Silverton Russet (#7), Canela Russet (#11), Centennial Russet (#12), Rio Grande Russet (#18)] in 2018 were developed by the Colorado program. Twenty-nine percent of the Russet Norkotah acreage (including line selections) was attributed to Colorado Russet Norkotah Selections 3 and 8. For reds, Sangre and Colorado Rose ranked #7 and #11 respectively. For chips, Chipeta ranked #10. For colored-fleshed specialties, Purple Majesty and Mountain Rose ranked #1 and #2 respectively.</li><br /> <li>The Texas Russet Norkotah selections (TXNS112, TXNS278, and TXNS296) collectively ranked third (in acreage) among the varieties accepted for seed certification in 2017. Russet Burbank and the Frito-Lay varieties ranked above these three selections. Certified seed of Russet Norkotah Texas clonal selections were planted in 7,500 acres in the USA in 2017 representing 7% of the national seed production, Certified seed acreage of the Texas Russet Norkotah strain selections continued to increase in 2018.</li><br /> <li>The Texas Russet Norkotah strains continue to be the prevalent varieties planted in Texas. Potato yields in Texas remain among the highest in the nation (440-465 cwt/a) in the summer crop producing states.</li><br /> </ul>
