Washington State University 2010 Tri-State/Regional Report MJ Pavek, NR Knowles, ZJ Holden, CD Hiles Process demand has declined along with acreage restrictions encouraged by the United Potato Cooperative. WA potato production fell by 30,000 acres between 2007 and 2010 (165,000 to 135,000 A). There are likely other factors affecting potato demand, none-the-less, we hope to see the Washington acreage increase in the near future. The interest in new varieties is on the rise. Over 18% of all seed lots in the 2010 WSU Seed Lot Trial were varieties that were newly developed or are new to the region. This is a record high and is up over 7% from just 3 years ago. In 1962, only eight varieties were entered into the trial, in 2002 23 varieties and in 2010 there were forty two entries. Varieties developed by the Northwest Potato Variety Development Program/PVMI accounted for 47% of the seed lots entered into the 2010 trial and included: Premier Russet, Classic Russet, Alpine Russet, Blazer Russet, Clearwater Russet, Highland Russet, Alturas, Ranger, Umatilla, and Gallatin Russet, Defender, and A0008-1TE. We are conducting N rate trials on Clearwater, Alpine, A0008-1TE, Sage, Owyhee, Classic, Ranger, Umatilla, and Russet Burbank. We conducted N-timing trials on Premier, Ranger, Umatilla, Blazer, and A0008-1TE. We are looking at in-row spacing of Clearwater and Premier. We hope to include phosphorous research on new cultivars in the hopes of identifying more efficient varieties. We conducted our largest Tri-State 10-hill and PYT trials this year and hope to continue the early testing in the future. Results from our research will be converted into PVMI cultural management guides when research is complete. We, as other Universities, are experiencing budget issues. Oregon State University 2010 Tri-State/Regional Report F Goktepe, S Yilma, B Charlton, C Shock, D Hane, D Culp As part of the Tri-State potato variety development program, the main objectives of the Oregon State University potato variety development and breeding program are selecting, evaluating and releasing new varieties, adaptive to the local conditions for both fresh and processing markets. The USDA/ARS, Aberdeen breeding program provides 80-85% of russet processing & fresh crosses each year as True Potato Seed (TPS). Breeding efforts at Oregon State University complement and enhance those of the USDA/ARS program in Aberdeen, ID by incorporating disease and pest resistances using multi-trait genotypic recurrent selection, as illustrated by the publication of marker-assisted selection (MAS) efforts for PVY resistance (Ottoman et al., and Vales et al., 2010) and the evaluation of genetic diversity in Tri-state clones (Karaagac et al., 2010). Introgression of genetic resistance focused on viruses, late blight, tuberworm, and rootknot and stubby-root nematodes. New molecular markers were added this past year to screen for resistance to Columbia root-knot nematode, late blight (RBgene), PVX, and potato cyst nematode. As expected, germplasm enhancement is a continuous application utilizing traits of interest from various sources including but not limited to wild species and land races. In 2010, the Oregon group conducted multiple field trials at four locations (Hermiston, Powell Butte, Corvallis and Klamath Falls). A total of 83,019 single hills were planted at Powell Butte and Klamath Basin R&E Center (KBREC). Approximately 473 clones were retained at Powell Butte and 291 at KBREC for further evaluation. Approximately, 50,000 seedling tubers were generated in Corvallis greenhouses with approximately 80% TPS derived from USDA/ARS Aberdeen, ID crosses and the remainder originating from USDA/ARS Prosser, WA and OSU. The largest tuber (A-size) from each tuberling was reserved for planting at Klamath Falls. The B-sized clones will be shared among collaborative institutes. The Oregon group led the release of two Tri-state varieties Sage Russet (AO96164-1) is a medium maturing high yield with a high proportion of U.S. No. 1 tubers, and excellent processing quality, & AmaRosa (POR01PG22-1) is a medium maturing fingerling potato clone with red skin and medium red flesh. Four advanced clones (POR01PG20-12, AO96141-3, POR03PG23-1 and POR02PG37-2) were recommended for 2011 releases. In addition, disease/pest/abiotic stress resistance trials were performed at Corvallis (late blight), Hermiston (Verticillium wilt/early die, PVY, PLRV, and tuber worm), and Klamath Falls (root-knot nematode). Due to recent budget constraints and changes in potato personnel a major restructuring of the Oregon variety development program is underway. As a result, Corvallis will focus on seedling tuber production, screening germplasm for resistances using molecular markers, and late blight screening. Hermiston and Klamath Falls will focus on variety development activities while Malheur will conduct early generation screening to abiotic stresses. Single-hill selection and subsequent seed increase will move from Powell Butte to Klamath Falls. The major breeding and selection activities will be continued with specific goals by following basic breeding principles. The major accomplishments of each station are outlined below: CSS: Made more than 270 successful crosses between promising long russets, chippers, reds and specialties clones and parental clones with cold sweetening resistance and known resistance to tuber worm, PVY, PLRV, late blight, corky ring spot, and nematodes. Produced more than 50,000 seedling tubers from TPS in Corvallis greenhouses for Oregon single-hill screening for planting in 2011. In addition, 40,000 B size seedling tubers will be sent to Texas A&M University and to other collaborative institutions. Evaluated agronomic and quality traits of Western regional red and specialty, PYT2 and statewide specialty trials in Corvallis. Evaluated potato sensory quality of specialty clones in statewide trials. Evaluated foliar and tuber late blight resistance of 367 potato clones in artificially inoculated trials in Corvallis. Two hundred seventy three early generation selections were evaluated in 12- and 4-hills plots. Fifty one advanced breeding selections and named varieties and 43 varieties from the National Late Blight Evaluation Program were evaluated in replicated trials. Maintained 85 potato accessions in the disease-free clone bank and produced ~300 lbs of disease-free pre-nuclear minitubers for research purpose. Performed molecular marker evaluations for PVY resistance on 176 single hills clones selected in 2009. A total of sixty three resistant clones with the PVY resistant gene Ryadg and with the PVY resistance gene Rysto were identified for further selection & testing. Screened 48 breeding clones from Aberdeen breeding program for PVY markers. Screened 10 clones selected in 2009 in single hills for resistant to Colombia root-knot nematodes (CRKN). Six clones were confirmed to have resistant the gene RMc1(blb), from S. bulbocastanum. A graduate student, Jose Ortega finished working on his Master degree project on PVY resistant derived from Premier Russet (A93157-6LS) and scheduled to defend his thesis. DNA fingerprinting of 54 varieties and advanced clones from the North West breeding; Program was conducted for variety identification and for PVP. Prepared PVP and release documents for new released varieties. Conducted three molecular breeding trials supported by OSU, Agricultural Research Foundation on PVY, late blight (RB gene) resistant, and Colombia root-knot nematodes. Evaluated 232 varieties in SolCAP collaborative trials. KBREC: Evaluated 70 advanced Tristate and Western Regional cultivars for fresh market, processing, and specialty use characteristics adaptable to the Klamath Basin. Evaluated 179 preliminary and advanced Oregon cultivars. Screened 59 4-hill chipping selections from 2009 single-hills grown in Klamath County and retained 15 for further evaluation. Screened 59 4-hill specialty selections from 2009 single-hills grown in Klamath County and retained 9 for further evaluation. Pre-selected, planted, harvested, and evaluated 26,656 single-hill seedling tubers and selected 291 for further evaluation. Summarized and published all red-skinned and specialty-type variety trial information from all participating regional cooperators. HAREC: Evaluated 33 advanced Tristate and Western Regional cultivars for fresh market, and processing use characteristics adaptable to the lower Columbia Basin. Evaluated 125 preliminary and advanced Oregon cultivars. Evaluated 759 Oregon selections and 112 USDA-ARS Aberdeen selections for visual reselection, with 70 and 23 cultivars being selected, respectively. Evaluated 56 Tristate and Western Regional cultivars for early die resistance. COARC: Produced and stored seed of 1,041 selections at Powell Butte for Oregon, Tristate, and Western Regional trials to be conducted in 2011. Packaged (5, 10, 25, and 50 lb sacks) and shipped 29,104 lbs. of seed to 19 research and 9 industry cooperators in 14 states. Pre-selected, planted, harvested, and evaluated 57,704 single-hill seedling tubers and selected 473 for further evaluation. Summarized and published all variety trial information from 3 Oregon sites. Maintained a web site featuring a potato variety database that generates various yield and quality reports. University of Idaho 2010 Tri-State/Regional Report 2010 Tri-State Technical Committee Meeting - Idaho Report Variety Development: No new varieties were released by the Idaho program last year. A97066-42LB, A98345- 1, A0008-1TE A00324-1, and A01010-1 were entries in the Western Regional Potato Variety Trials. A01010-1 appears to have potential as a dual purpose russet and also has high levels of vitamin C and protein. A0008-1TE is under consideration for release, primarily for early fresh production. Average yields in early harvest trials in Idaho, Oregon and Washington have been comparable to Russet Norkotah, but it has higher levels of vitamin C and protein. Additional research will be conducted in 2011 to assess fresh pack potential for A0008-1TE under commercial conditions. Seven clones were evaluated last year in the Tri-State Red/Specialty Trial, including, A02267-1Y, A02267-5PY, A03576-5Y, NDA8512C-1R, NDA050237B-1R, A05173-2RY, and A05177-4RY. In addition, A99326-1PY, A99331-2RY A00286-3Y and A99433-5Y were evaluated in the Western Regional Red/Specialty Trial. A99326-1PY is under consideration for release in 2011. It is a purple-skinned, yellow fleshed clone with good culinary quality and medium yield potential. Continuing Research Studies: In 2010, 36 trials were conducted at 7 locations across southern Idaho, consisting of advanced and cooperative variety trials, grower variety trials, genetic studies, and management studies. Efforts to enhance potato vitamin C content continued, with breeding efforts progressing to increase levels of ascorbic acid. In addition, screening studies were again conducted in 2010 in an effort to develop russets with good yield and quality characteristics and resistance to corky ringspot. The study is progressing well with a number of russets with good type being identified with good corky ringspot resistance. Management Studies: Nitrogen Responses - In 2010, we continued a multi-year study in which we compared the nitrogen use efficiency of varieties released by the Northwest Potato Variety Development Program with that of Russet Burbank. The varieties included Alpine Russet, Alturas, Classic Russet, Clearwater Russet, Highland Russet, Premier Russet, Umatilla Russet and Western Russet. In each of these trials, the varieties received N fertilizer at rates ranging from 0 to 360 lb N/acre, with the N split between pre-plant (60%) and in-season (40%) applications. We compared the yield produced per lb of N fertilizer for each variety at the point of maximum yield. With the exception of Highland Russet, all of the new varieties had appreciably higher N use efficiency than Russet Burbank at maximum yield, with improvements ranging from 118 to 170% of RB. Nitrogen requirements for a given yield goal, were about 40% less than Russet Burbank for Alturas and 20-25% less than Russet Burbank for Alpine Russet, Classic Russet, Clearwater Russet and Premier Russet. Western Russet required about 10% less N than Russet Burbank, while Highland Russets N requirement was similar to Russet Burbanks Irrigation Responses - In an additional study conducted at Aberdeen in 2010, Alpine Russet, Alturas, Clearwater Russet, Premier Russet Umatilla Russet and Russet Burbank were irrigated during the growing season at; 1) 100% ET, 2) 75% ET, or 3) 50% ET. Premier Russet, Alpine Russet and Clearwater Russet had the highest total and US No. 1 yields with irrigation at 100% ET. Premier Russet, Alpine Russet and Clearwater Russet also had the highest US No. 1 yields with the 75% ET and 50% ET irrigation treatments. Response to Reduced Pesticide Applications - Studies were conducted in 2010 as part of an ISDA-SCBG research project at Parma and Aberdeen to evaluate the potential for reducing pesticide rates on new varieties from the Tri-State. Varieties included in this study were Alpine Russet, Alturas, Clearwater Russet, Premier Russet and Umatilla Russet, and Russet Burbank. Preliminary results have shown that pesticide rates for some of these varieties can be reduced in comparison to Russet Burbank. Texas 2010 Tri-State/Regional Report 84,644 first year seedlings, resulting from 657 different parental combination or families (crosses), were grown for selection on the Barrett Farm (16,860) near Springlake and on the CSS Farm (67,784) near Dalhart. 573 original selections were made. 14 clones were intercrossed to produce 11 families. We received seedlings tubers from the Idaho (6,860), Oregon (30,696), Colorado (20,020), and North Dakota (11,616) breeding programs. We grew 33,726 tuberlings in the greenhouse from true seed. Evaluation trials were conducted at Weslaco (Winter - December 6 planting, April 14 harvest), Springlake (Spring  April 1 planting, August 2, 5, 24, and 26 harvests), and Dalhart (Fall  May 6 planting, September 6,20 and October 4, 18, 20 harvests) 693 advanced selections/new cultivars were tested in 40 separate trials. Western Regional Trials were conducted at both Springlake (Chip, Russet and Red/Specialty) and Dalhart (Chip). The Texas Program had three entries in the Western Regional Russet Trial (AOTX95265-1Ru, AOTX96216-2Ru, and AOTX96265-2Ru) and three entries in the Western Regional Red/ Specialty Trial (BTX2332-1R, COTX94216-1R, COTX94218-1R). The Texas program had 13 entries (ATTX88654-2P/Y, ATTX98510-1R/Y, ATTX01180-1R/Y, BTX2103-1R/Y, COTX01403-4R/Y, TX1674-1W/Y, AOTX96084-1Ru, AOTX98152-3Ru, ATX9332-12Ru, AOTX91861-4R, ATTX98453-11BR, NDTX5003-2R, and NDTX5438-11R) in theSouthwestern Regional Trials. Field day was held on July 15 at Springlake and was well attended. Initiated a major expansion of the chip program with participation in the National Breeders Chip Trial. Continued investigating activity of bioactive compounds from potato on prostate cancer in vivo. Virtually all of the russet potatoes grown in Texas in 2010 were the improved Texas Russet Norkotah strains. Over the past several years, Texas recorded the highest Summer crop yields in the nation (440-465 Cwt/A) among the 11 states producing a summer crop. PVP was granted for Stampede Russet and Rio Rojo in 2010. A major preoccupation of the program continues to center around the Zebra Chip effort. Emphasis on virus testing and clean-up continued. Colorado State University 2010 Tri-State/Regional Report The Colorado Potato Breeding and Selection Program intercrossed 99 parental clones in 2010 in two separate crossing blocks. The emphasis of the first crossing block was russet, chipper, specialty cultivar development and PVY resistance. The second crossing block emphasized russet and specialty cultivar development and PVY resistance. Seed from 278 combinations was obtained. Approximately 57,200 seedling tubers representing 218 families were produced from 2008 and 2009 crosses for initial field selection in 2011. These seedlings represent crosses segregating primarily for russet, reds, specialty types, and resistance to late blight, PVY, corky ringspot, and nematodes. Second through fourth size seedling tubers will be distributed to Idaho (USDA-ARS), Minnesota, North Dakota, Oregon, Texas, Wisconsin, and Alberta, Canada (Agriculture Canada). Colorado grew 84,924 first-year seedlings representing 478 families in 2010, with 623 selected for subsequent planting, evaluation, and increase in future years. A portion of these seedlings were obtained from the USDA-ARS (Aberdeen, Idaho and Beltsville, Maryland, MD), Agriculture Canada, Texas A&M University, North Dakota State University, and Oregon State University. Another 1,166 clones were in 12-hill, preliminary, and intermediate stages of selection. At harvest, 370 were saved for further increase and evaluation. Fifty-five advanced selections were saved and will be increased in 2011 pending further evaluation. Another 281 selections and cultivars were maintained for germplasm development, breeding, and other experimental purposes including seed increase/maintenance. Field trials conducted in 2010 included: Preliminary Trial, Intermediate Yield Trial, Intermediate Specialty Yield Trial, Advanced Yield Trial, Advanced Fingerling Trial, Southwestern Regional Russet Trial, Southwestern Regional Red Trial, Southwestern Regional Chip Trial, Southwestern Specialty Trial, Western Regional Russet/Processing Trial, Western Regional Red Trial, Western Regional Specialty Trial, San Luis Valley Chipping Trial, and Western Regional Chipping Trial. All trials are grown under low input conditions, primarily for reduced nitrogen and fungicide. A total of 212 samples are in the process of being evaluated for two or more of the following postharvest characteristics: blackspot susceptibility, storage weight loss, dormancy, enzymatic browning, specific gravity, french fry color, french fry texture, and chip color. Advanced selections evaluated in the Southwest Regional Trials, Western Regional Trials, or by Colorado producers in 2010, included 6 russets (AC99375-1RU, CO97087-2RU, CO98067-RU, CO99053-3RU, CO99053-4RU, and CO99100-1RU), 2 reds (CO99076-6R and CO99256-2R), 9 chippers (AC01151-5W, CO95051-7W, CO97043-14W, CO00188-4W, CO00197-3W, CO00270-7W, CO02024-9W, CO02033-1W, and CO02321-4W), and 8 specialties (AC97521-1R/Y, AC99329 -7PW/Y, ATC00293-1W/Y, CO97226-2R/R, CO97232-2R/Y, CO00412-5W/Y, CO01399-10P/Y, TC02072-3P/P). An additional 12 selections are being considered for exclusive release. Included in this group is CO95051-7W. Since the WR Regional Chip Trials it has undergone extensive testing in the USPB/SFA Chip Trials and the USPB Fast Track program. This round white selection has excellent chip color after long term storage. Plant Variety Protection was granted to Rio Grande Russet in 2010. Since 1975, there have been 27 potato cultivars/clonal selections released by Colorado State University or in cooperation with other agencies. Colorado State University releases accounted for 59% of the 55,500 acres planted to fall potatoes in Colorado in 2010. Primary Colorado cultivars planted were Russet Norkotah-S3 (24%), Canela Russet (13%), and Rio Grande Russet (7%). Colorado cultivars and clonal selections accounted for 44% of the 12,053 acres of Colorado certified seed accepted for certification in 2010. Advanced Colorado selections accounted for another 1% of the seed acreage. Three of the top 10 russet cultivars grown for seed in the U.S. [Canela Russet (#7), Rio Grande Russet (#8), Russet Norkotah-S3 (#9) in 2009 were developed by the Colorado program. For reds Sangre-S11 ranked #7. For colored fleshed specialties, Mountain Rose and Purple Majesty both ranked #1 among red- and purple-fleshed cultivars. In 2010, horticultural evaluations were conducted on 23 potato cultivars and advanced selections in 16 trials at 7 locations in the San Luis Valley of Colorado. Tests included 9 russets, 4 reds, 10 specialties including 2 fingerlings. The trials assessed the influence of different cultural management practices on plant growth, development, tuber yield, tuber size distribution, and tuber quality of potato cultivars, in an effort to establish optimum management guidelines for each cultivar. Studies conducted in 2010 included the response of four potato cultivars to different nitrogen (N) application rates. Nitrogen rate treatments ranged from 0 (control) to 202 kg N/ha. The influence of in-row seed spacing on the performance of five potato cultivars was evaluated. Potato cultivars were planted at 25, 30, 35, and 40 cm. The effect of N application timing on the performance of a newly released potato cultivar Mesa Russet was concluded in 2010. Pre-plant N application rate treatments included 0, 68, 90, 112 kg N/ha, and a control, where no N was applied. Where N was applied, the remainder of the total N recommended for the cultivar was applied in three split applications during the crop growing season. The effect of compost and N application rate was concluded in 2010. Compost application rate treatments ranged from 2.2 to 11.2 Mg/ha. Within each compost application rate treatment N was applied either at the full recommended rate or one half of the recommended rate for the cultivar. Specific results of these trials will be available at a later date. 2010 Tulelake Potato Research Update UC Intermountain Research & Extension Center, Tulelake, CA Variety Development: Evaluated 44 Western Regional, 24 Southwest Regional, and 11 entries of local interest for the Late Russet, Red/Specialty and Chipper Variety Trials to look for entries suitable for the Klamath Basin. Evaluations included variety susceptibility to Verticillium wilt. Cultural Management: Seed Spacing Trial: Evaluated 6 Chip varieties, one was WR entry CO97043-14W, at 4 different seed spacings of 6.75, 9.25, 12.5, and 15 inches Pest Management: Herbicide Trial: Evaluated efficacy and crop safety of varying rates and tank-mixes of Outlook, Prowl H2O, Matrix, and Metribuzin on Russet Norkotah. Disease management trials examining control methods for Black dot and VerticilliumWilt. PVMI Report: Tri-State & Western Regional Technical Meeting 2.1.11. Jeanne Debons, Executive Director PVMI PVMI has collected $88,500 in license fees and $329,527.28 in royalties. The breakdown of where the funds are coming from is approximately 1/3 from the Tri-States, 1/3 from the US and 1/3 from outside the US, meaning 2/3 of the total comes from outside the Tri-State area. The license fees were reduced in January 2009, this has been received positively with more licenses administered this past year. For the first year in 2009 Ivory Crisp provided royalty income as will Alturas in 2010. This will help to offset the losses by Premier having being dumped and Classic problems encountered with fresh packing. All seed growers who grow Classic have been sent New Classic Russet Management Guidelines prepared by Jeff Stark and Mark Pavek. A successful RFP and exclusive license has been granted to Klamath Basin Fresh Direct LLC, Dan Chin for Purple Pelisse which is currently being managed in the US and Canada. The Coop is also sublicensing to other growers including Potandon, Childstock Farms and others. PVMI has worked to create both Tri-State and variety marketing and promotional materials to be distributed at exhibitions and through the website www.pvmi.org. A new community site is available to be used by all members of the industry to buy, sell and blog about potatoes http://community.pvmi.org. $33,792 was paid by PVMI to the Universities for PVP costs incurred by them since 2006. Note also that an additional $15,213 was paid for International PBR, this includes trials, application and administration costs associated with registering the new varieties in Canada. Future PBR costs will be covered by parties bringing varieties to new countries under the Sub-License Agreement. The sum of $100,000 was distributed to the Universities for the second year running for further distribution in aid of the research and breeding efforts, as it is one of the principal objectives of PVMI. PVMI is concentrating in supporting the existing Tri-State varieties as well as getting them evaluated in foreign markets, where potential for income ($1.00/CWT seed sold) is high, and Tri-State has an excellent international reputation. PVMI is also working with Lorie Ewing to get more money into the Potato Lab at University of Idaho.
