Approval of the agenda: Motion to accept by Bob Thornton and seconded by Jeff Koym. The motion was unanimously accepted. Approval of the minutes from 2009 meeting: Motion to accept by Jeff Stark and seconded by Dave Holm. The motion was unanimously accepted. Administrative Advisors Report: Donn Thill talked about his role as the administrative advisor and discussed the current status of the report. Renewal of Project: Chuck Brown said that this subject was already discussed in the previous meeting. State Reports: Oregon: Isabel Vales said that everything was covered in their Tri-State report. (See attached reports) Washington: Mark Pavek and Rick Knowles said that everything was discussed during the Tri-State Report. (See attached report). Idaho: Jeff Stark talked about some work that he and Mike Thornton have been working on with sustainability, especially with fumigants. Jeff Stark also talked about finding some information on carbon footprints. (See attached report). California: The California representative said that they would like to continue doing work with the Western Regional group. Colorado: Dave Holm said that Colorado has released a variety that was in our Regional trial named Mesa Russet, clone name CO94035-15Ru. He said that their budget cuts were not as bad as most other states. (See attached report). Texas: Creighton Miller gave the Texas report. Texas is looking to find a variety that stores better than Snowden and looks better than Atlantic. Zebra Chip is a large concern in their state. More than 1.6 Million dollars have been invested through legislature to help solve this problem. They are also going to continue the research in collaboration with Roy Navarre on color cancer treatment from potato extracts (See attached report) PVP updates: Jeanne Debons discussed PVP updates. Visit website at http://www.pvmi.org/ for more information. PVMI Report: Jeanne Debons gave the PVMI report that was scheduled to be given during the Tri-State meeting. Royalty money has started returning to the Universities that have done research on them, this past year the board granted $100,000 to be distributed back to research Universities. There has been a restructuring of fees this past year. Visit PVMI.org for more information. Jeanne mentioned that they are going to start advertising on the PVMI website. Jeanne discussed the breakdown of the distribution of royalty money and how much each group (University, ARS, USDA, etc) gets. Centralization of future sites: Jeff Stark mentioned that it had been decided last year that with Idaho hosting they would have the meetings in Boise the second Tuesday in February of 2011. Early and Late Trials (Rich Novy): Rich Novy gave the Western Regional trial data. Peggy Bain asked if we should separate the data by the harvest dates. It was said that all the information that a person would need to see the difference between early and late harvest is represented by table 1. It was decided to leave the trials as they are. Rich Novy asked if people would like to have an additional column in each table that highlighted the top three and bottom three performing varieties in each category. Everyone agreed that it would be helpful. Rich and Brian Schneider will put that in their reports from now on. Postharvest Results (Rick Knowles): Rick Knowles gave the postharvest report for the Regional trial. Knowles referred to the WSU 2009 Potato Cultivar Yield and Postharvest Evaluations. He noted that the clone A98345-1 did very well in the overall postharvest ratings, but that it had a significant problem with mottling after 44 days in storage.

Washington Accomplishments: " From the Red and Specialty Trial, clone POR02PG37-2 has shown extreme promise as a variety that could squeeze out Yukon Gold. The issue with Yukon Gold is that it tends to get too large and produces too few of tubers. POR02PG37-2 has bright pink eyes, deeper yellow flesh, smaller size distribution, more tubers per plant than Yukon and tastes great. Another variety to keep your eye on as a potential early market fresh pack potato is A0008-1TE. It has competed rather well with Russet Norkotah in the early harvest trials, and does rather well when produced for a later harvest. " We completed a three year study examining in-season nitrogen rates for two new cultivars. Despite the fact that some growers have been reducing N applications to Alturas and Premier Russet compared to typical Russet Burbank fertilization, we have found that growers in the Columbia Basin may actually be compromising their economic return by doing so. Rather than recommend the lbs/A N to apply, we recommend keeping petiole and soil N within ranges that brought the highest economic return in our study. " Along with Dr. N.R. Knowles and team, we completed the second year of a three year study examining nitrogen application timing to determine the effects of in-season N timing on whole plant morphology and physiology and economic value from several late harvest varieties. Ranger Russet, Umatilla Russet, and Premier Russet were grown under the different N application regimes during 2008 & 2009. Data from both years are inconclusive. Data from 2009 was likely compromised due to unexpected N release within the soil during June that provided all treatments ample N during the early portion of the season. Despite the inconclusive results we plan to continue this study one more year. " Similar to the study above (No. 5), two varieties (AO96141-3 and Blazer Russet) were grown under four different in-season application/rate schemes in an effort to establish recommendations for an early harvested crop. Similar to the study above, the results from 2008-09 were inconclusive; however, we hope to continue this study for another year to help us understand the best ways to grow these and other cultivars for an early harvest. " We initiated a new study during 2009 examining the influence of 4 in-season nitrogen rates (25- 125- 225- 325-lbs/A N) on eight varieties: Alpine Russet, Classic Russet, Clearwater Russet, Owyhee Russet, Ranger Russet, Russet Burbank, Umatilla Russet, and A0008-1TE. Petiole and soil data indicate treatment differences, as do the yield and economic return. However, this is the first year of three years, and we will not make any serious conclusions until the study is completed at the end of 2011. Oregon Accomplishments: " Produced and stored seed of 1167 selections at Powell Butte for Oregon, TriState, regional, chip, specialty, and other trials to be conducted in 2010.

" DNA fingerprinting of 54 varieties & advanced clones from the North West breeding Program was conducted for variety identification & for PVP. " Prepared PVP and release documents for new released varieties. Idaho Accomplishments: " Plant variety protection applications were filed for Classic Russet, Alpine Russet and Clearwater Russet in 2009. However, no new varieties were released by the Idaho program last year. A96814-65LB and A98345-1 were new entries in the Western Regional Potato Variety Trials, while A97066-42LB and A0008-1TE were evaluated for a second year. A00324-1, A00727-1 and A01010-1 were evaluated last year in the Tri-State Variety Trial. Of the three clones, A01010-1 appears to have the greatest potential as a dual purpose russet and also has high levels of vitamin C and protein. " Six clones were evaluated last year in the Tri-State Red/Specialty Trial, including A99331-2RY, A99433-5Y, A02267-1Y, A02267-5PY, A03576-5Y and NDA8512C-1R. In addition, A99326-1PY, A00286-3Y and A00293-2Y were evaluated in the Western Regional Red/Specialty Trial. " In 2009, 34 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 2009 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 commercially acceptable russets being identified with good corky ringspot resistance. Texas Accomplishments: " 56,501 first year seedlings, resulting from 386 different parental combination or families (crosses), were grown for selection on the Barrett Farm (28,271) near Springlake and on the CSS Farm (28,230) near Dalhart " 279 original selections were made " 31 clones were intercrossed to produce 45 families " We received seedlings tubers from the Idaho (7,589), Oregon (10,615), Colorado (19,928), and North Dakota (10,615) breeding programs. Dave Holm, (Colorado) also provided mini tubers (1,000) from advanced Texas selections for seed increase. " We grew 21,246 tuberlings in the greenhouse from true seed " Evaluation trials were conducted at Springlake (Spring April 7 planting, August 3 and 17 harvests), and Dalhart (Fall April 29 planting, September 13, 28 and October 12 harvests) 654 advanced selections/new cultivars were tested in 44 separate trials " Western Regional Trials were conducted at both Springlake (Russet and Red/Specialty) and Dalhart (Chip) " The Texas Program had five in the Western Regional Red/ Specialty Trial (ATTX98453-6R, BTX2332-1R, COTX94216-1R, COTX94218-1R, and NDTX4784-7R)) " The Texas program had 21 selections (ATTX98493-1R/Y, ATTX98518-5PU/Y, ATX9132-2Y, BTX2103-1R/Y, PORTX03PG25-2R/R, Sierra Gold-2, Sierra Gold-3, TXYG055, TXYG057, TXYG079, TXYG098, TXYG105, TXYG107, AOTX95265-1RU, AOTX96265-2RU, ATX9332-12RU, ATX97232-1RU, ATTX98453-11BR, ATTX01178-1R, COTX00104-7R, and NDTX5003-2R) in the Southwestern Regional Trials " Field day was held on July 22 at Springlake and was well attended " Continued expanded emphasis on evaluating chip selections as well as colored flesh selections " Work continued on screening for and identifying important phytochemicals in potato and its wild relatives including evaluating these compounds for anti-cancerous properties in human prostate cancer cells and publication of results of this work " Virtually all of the russet potatoes grown in Texas in 2009 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 is pending for Stampede Russet and Rio Rojo " The major new program addressing Zebra Chip was continued. Emphasis on virus testing and clean-up continued Colorado Accomplishments: " The Colorado Potato Breeding and Selection Program intercrossed 109 parental clones in 2009 in two separate crossing blocks. The emphasis of the first crossing block was russet and specialty cultivar development. The second crossing block emphasized russet and specialty cultivar development and corky ringspot resistance. Seed from 399 combinations was obtained. " Approximately 55,960 seedling tubers representing 253 families were produced from 2007 and 2008 crosses for initial field selection in 2010. These seedlings represent crosses segregating primarily for russet, reds, specialty types, and resistance to late blight, PVY, and 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 81,644 first-year seedlings representing 481 families in 2009, with 810 selected for subsequent planting, evaluation, and increase in future years. A portion of these seedlings were obtained from the USDA-ARS-Idaho, Agriculture Canada, Texas A&M University, and Oregon State University. Another 1,232 clones were in 12-hill, preliminary, and intermediate stages of selection. At harvest, 372 were saved for further increase and evaluation. Forty-eight advanced selections were saved and will be increased in 2010 pending further evaluation. Another 267 selections and cultivars were maintained for germplasm development, breeding, and other experimental purposes including seed increase/maintenance. " Field trials conducted in 2009 included: Preliminary Trial, Intermediate Yield Trial, Intermediate Specialty Yield Trial, Advanced Yield Trial, Southwestern Regional Russet Trial, Southwestern Regional Red 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 producers in 2009, included 10 russets (AC96052-1RU, AC99375-1RU, CO94035-15RU, CO95172-3RU, CO97087-2RU, CO98067-7RU, CO98368-2RU, CO99053-3RU, CO99053-4RU, and CO99100-1RU), five reds (CO98012-5R, CO99076-6R, CO99256-2R, CO00277-2R, and CO00291-5R), seven chippers (CO95051-7W, CO96141-4W, CO97043-14W, CO97065-7W, CO00188-4W, CO00197-3W, and CO00270-7W), and 17 specialties (AC97521-1R/Y, AC99329-7PW/Y, AC99330-1P/Y, ATC00293 -1W/Y, CO97222-1R/R, CO97226-2R/R, CO97227-2P/PW, CO97232-1R/Y, CO97232-2R/Y, CO97233-3R/Y, CO99045-1W/Y, CO00379-2R/Y, CO00405-1RF, CO00412-5W/Y, CO00415-1RF, CO01399-10P/Y, and VC1009-1W/Y). Mesa Russet (CO94035-15RU) was named in 2009. Mesa Russet is a high yielding, dual-purpose russet. It has a medium maturity and a high percentage of US #1 tubers. It is resistant to second growth, blackspot bruise, shatter bruise, powdery scab (tuber and root galling) and verticillium wilt. Mesa Russet has also shown potential to fry after storage. " Since 1975, there have been 27 potato cultivars/clonal selections have been released by Colorado State University or in cooperation with other agencies (Table 1). Colorado State University releases accounted for 61% of the 56,000 acres planted to fall potatoes in Colorado in 2009. Colorado cultivars and clonal selections accounted for 45% of the 11,470 acres of Colorado certified seed accepted for certification in 2009. Advanced Colorado selections accounted for another 2% of the seed acreage. Four of the top 20 russet cultivars grown for seed in the U.S. [Canela Russet (#7), Rio Grande Russet (#8), and Russet Norkotah-S3 (#9), Russet Norkotah-S8 (#15)] were developed by the Colorado program. For the red category, Sangre-S11 ranked #7. For colored-fleshed specialties, Mountain Rose and Purple Majesty ranked #1 among red and purple-fleshed cultivars.

An extension bulletin on storage management for Classic Russet was published last year, www.kimberly.uidaho.edu/potatoes/CIS1167.pdf). Management guides for Classic Russet and Premier Russet are also being developed.
