Target Audience:Farmers, processors, quick service restaurant industry, industry stakeholders (agricultural chemical and fertilizer companies, food processors, equipment manufacturers, etc.). Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?The NWPVD program provides continuing opportunities for training personnel in the science of breeding and genetics, variety development, agronomic management, and postharvest handling, storage and processing quality evaluation of a diverse array of germplasm. On average, the multi-state project engages three to four graduate students, three postdoctoral associates, five technical, and numerous undergraduate students in the project annually. Extension personnel and industry stakeholders also participate in efforts to grow and evaluate the clonal entries on an annual basis. Many of the graduate students who have worked in this program are employed in professional and management positions in the potato industry. How have the results been disseminated to communities of interest?Dissemination of detailed research results from the NWPVD Program occurs annually at meetings of the Tri-State and Western Regional Technical Committees (which includes university, industry/stakeholder, and USDA-ARS members), and in written form through publication of the USDA-ARS Western Regional Trial Report and the WSU Potato Cultivar Yield and Postharvest Quality Evaluations Report. Both of these publications are freely available in written and electronic formats: https://www.ars.usda.gov/pacific-west-area/aberdeen-id/small-grains-and-potato-germplasm-research/docs/western-regional-tri-state-potato-variety-trial-reports/ and https://potatoes.wsu.edu/trials/ Additionally, results from the Northwest program are communicated directly to stakeholders annually through oral presentations and related proceedings articles at the Washington/Oregon Potato Conference (Kennewick, WA), Western Washington Potato Conference (Mt Vernon, WA), Idaho Potato Conference (Pocatello, ID), and Hermiston Farm Fair & Trade Show (Hermiston, OR). Potato field days showcasing variety trials and related management research are held annually at the WSU Research Unit at Othello, WA, WSU Northwest Washington Research & Extension Center at Mt Vernon, WA, and Hermiston Agricultural Research & Extension Center (Hermiston, OR). Varieties released from the program are managed by the Potato Variety Management Institute, which summarizes phenotypic data and articulates strengths and weaknesses of released varieties along with cultural and storage management information on the PVMI website (https://www.pvmi.org/) Further agronomic and postharvest management information is made available to researchers and stakeholders on the University of Idaho potatoes websites (https://www.uidaho.edu/cals/potatoes/varieties & http://www.uidaho.edu/cals/potatoes/storage) and Oregon Statewide reports are available at (https://extension.oregonstate.edu/people/sagar-sathuvalli). Collectively, these efforts expedite the earliest possible adoption of new releases, which is a strength of the Northwest Program. The PI's also communicate research results nationally and internationally through oral and poster presentations at annual meetings of professional societies (e.g., Potato Association of America, American Phytopathological Society) and via publication of refereed journal articles. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Impact: Fifty-five varieties have been released by the NWPVD program across the past 40 years. Many NWPVD varieties have been widely adopted; among these varieties, Umatilla Russet, Ranger Russet, Clearwater Russet, and Alturas have greatly benefited the United States and Northwest potato industry and as such, were the 3rd, 4th, 7th, and 15th most widely grown cultivars in the United States in 2022. Varieties released by the NWPVD Program are now produced on approximately 170,000 acres in the Pacific Northwest with value to growers estimated at approximately $770 million. NWPVD varieties represented 38%, or 349,000 acres, of the 2022 fall crop nationally. The estimated 2022 US farm-gate value of NWPVD varieties was more than $1.57 billion. An economic analysis revealed that every dollar invested in the NWPVD program results in a 39% return on investment. Accomplishments: Between 2015 and 2023, 14 potato varieties were released by the NWPVD, including: Pomerelle Russet, Mountain Gem Russet, Payette Russet, Targhee Russet, TerraRossa, Smilin' Eyes, Echo Russet, Castle Russet, Purple Iris, Deliciae, La Belle Russet, Galena Russet, Becca Rose, and Rainier Russet. All varieties developed by the Northwest Program have been licensed to the Potato Variety Management Institute (PVMI), a non-profit organization working on behalf of the program to promote and market varieties since 2005. Detailed information, including management guidelines for NWPVD cultivars are available on the PVMI websites: (www.pvmi.org). Marker-assisted variety development and selection are increasingly important for improved program efficiency and success. In 2023, marker assisted selection was performed in Oregon on second field year selections for PVY and CRKN resistances and selected 10 PVY resistant and 6 CRKN resistant selections. A post-doctoral associate joined the Aberdeen program in 2019 to continue further research efforts in developing markers useful for marker-assisted selection with his research identifying QTLs associated with tuber shape and specific gravity that can be used in developing markers useful in marker-assisted selection. Disease resistance is a NWPVD priority. The Aberdeen breeding program is progressing in the evaluation and identification of germplasm with genetic resistances to potato viruses X and Y (PVX, PVY), Potato leafroll virus (PLRV), late blight (foliar and tuber), potato cyst nematodes (PCN), Verticillium wilt (VW), zebra chip and potato psyllid (the insect vector for Liberibacter responsible for zebra chip). In fact, six entries in the NFPT in 2023 exhibited extreme resistance to PVY. In addition, Payette Russet is an example of our efforts in breeding for extreme virus resistance to all PVY strains (conferred by the Rysto gene). Additionally, Payette has resistance to late blight and common scab, and is moderately resistant to VW, early blight, and CR. Progress has continued in the development of potato varieties having resistance/tolerance to the tuber necrotic viruses, Potato mop-top virus (PMTV) and Tobacco rattle virus (TRV) responsible for corky ringspot disease. A manuscript detailing the inheritance and mapping of QTLs associated with resistance to these two viruses has been accepted for 2023 publication in the American Journal of Potato Research following revisions (submitted by Noelle Anglin, PhD, USDA-ARS). Improved plant characteristics, such as nutrient (fertilizer) and water-use efficiency, are essential to keep U.S. growers globally competitive, maintain limited resources, and reduce greenhouse gas emissions. Between 2019 and 2022, four NWPVD releases, Alturas, Clearwater Russet, Ranger Russet, and Umatilla Russet used between 4% and 14% less water than Russet Burbank to produce equivalent tuber yields. Pavek et al. (2018) investigated improving land- and input-use efficiency of 5 cultivars, 4 of which originated from the NWPVD program, through a reduction in row width. Grower returns and yields improved an average of 4% by reducing row width by 5 cm, while using less inputs and land. Pavek et al. (2017) found improvements in N use efficiency of some of the NWPVD varieties. Pavek and team also showed that NWPVD varieties differed substantially in their ability to assimilate and efficiently utilize fertilizer N. They related seasonal changes in total plant and tuber N uptake rates to cumulative absorbed solar radiation to develop standardized N uptake reference curves for each variety. These standard curves provide a basis for comparing N uptake rates from subsequent potato crops. Cultural and storage management guides are continually being developed as new NWPVD varieties are released to provide the U.S. potato industry with critical information for the successful production and storage of these new varieties. Improved human nutrition One medium-sized potato can supply 45% of the daily value of Vitamin C (ascorbate) for an adult and potatoes contribute ~19% of ascorbate to our diets. Ascorbate in cultivated potatoes ranges from about 11 to 40 mg/100 g FW and levels can be increased through traditional breeding and transgenic approaches. However, ascorbate is lost rapidly from tubers after harvest. Studies with NWPVD varieties characterized vitamin C accumulation in relation to gene expression during tuber development and demonstrated that loss during storage is genotype-dependent. Selecting for reduced postharvest loss will greatly improve potatoes as a dietary source of vitamin C and is routinely evaluated the program.

Impacts
What was accomplished under these goals? Collectively, 29 agronomic trials assessing best management practices (BMPs) for Northwest Potato Variety Development (NWPVD, also known regionally as the Tri-State (ID, OR,WA) Program) breeding clones were conducted during 2021 in Aberdeen and Kimberly, ID, Hermiston, OR and Othello WA. Several trials examined nitrogen use efficiency of advanced selections from the breeding program with that of the industry standard, Russet Burbank. The nitrogen use efficiency for several for these six clones ranged between 10-25% better than that of Russet Burbank. Reducing fertilizer applications per unit of yield 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 seed management practices, seed piece spacing, row width spacing, plant maturity, and nitrogen management guidelines for new and previously released NWPVD varieties. Trials in 2022 examine spatial arrangements of plants, calcium uptake, potassium requirements of three varieties, cut and whole seed, plant maturity, and nitrogen use efficiency on advanced clones. Most recent variety releases from the NWPVD program include Rainier Russet, Galena Russet, and La Belle Russet. Ten other varieties released between 2015 and 2021: Pomerelle Russet, Mountain Gem Russet, Payette Russet, Targhee Russet, TerraRossa, Smilin' Eyes, Echo Russet, Castle Russet, Purple Iris, Deliciae, La Belle Russet, Galena Russet, and Rainier Russet. All varieties developed by the Northwest Program have been licensed to the Potato Variety Management Institute (PVMI), a non-profit organization working on behalf of the program to promote and market varieties since 2005. Detailed information, including management guidelines for NWPVD cultivars were published on the PVMI websites: (www.pvmi.org). Cold-sweetening resistance is also an objective of the program and Clearwater Russet, Payette Russet, and most recently, Galena Russet (Spear et al., 2021) are examples of our success in this area. The enhanced cold-sweetening resistance of Clearwater Russet contributed significantly to its approval by McDonald's for processing in the PNW. Such low-sugar varieties also contribute to reductions in acrylamide formation in processed potato products, with reducing sugars being a primary contributor. One hundred and fifty-four parental clones were grown in the greenhouse in 2021 at Aberdeen, ID and hybridizations made among them for the generation of true potato seed--the starting point for the generation of new populations in our breeding program at Aberdeen, Idaho. Three hundred and forty-nine families representing 407,000 true potato seed were generated and extracted from potato berries from 2021 hybridizations. Ninety-three thousand seedling tubers representing 580 unique families generated from the Aberdeen program and from other state breeding programs were planted at Aberdeen and Tetonia, ID in 2021 with selections made among them; selected clones became our second field year (12-hill selections) in 2022. An additional 1,532 second-field year (12-hill) selections were also planted in 2021. Clones selected from the 2021 12-hill trial will advance and be planted into 2022 replicated field trials. In 2021, 11 entries from the Aberdeen program were entered in advanced Tri-State and Western Regional (CO, ID, OR, WA, TX) agronomic and processing trials to assess their performance relative to industry standards. Early and late harvest performance for each clone was tested at each trial location. Seventeen NWPVD clones will be evaluated under early and late harvest conditions in the 2022 Tri-State and Western Regional Trials. New varieties will continue to be released in cooperation with the University of Idaho Nuclear Seed Program, private seed growers in the state, and the processing and fresh pack industries. Forty-two NWPVD breeding clones were entered in the 2022 National Fry Processing Trial (NFPT) and grown in six states, including WA, OR, and ID. The NFPT serves to identify and fast-track new varieties for rapid adoption within the U.S. processing industry. Desirable traits include low acrylamide and acceptable agronomics and processing ability. Five of the 42 entries are being tested at the advanced, Tier 3 level; 13 of them at mid, Tier 2 level and the remaining 24 clones were tested within the Tier 1 level. 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--in fact, nine entries in the NFPT in 2021 exhibited extreme resistance to PVY. Advanced clones were entered into disease trials in Aberdeen and Kimberly Idaho and screened for early blight, common scab, and viruses PVX, PVY, and PLRV. In addition, clones were evaluated for dry rot and soft rot susceptibility. Progress has continued in the development of potato varieties having resistance/tolerance to the tuber necrotic viruses, Potato mop-top virus (PMTV) and Tobacco rattle virus (TRV) responsible for corky ringspot disease. An Aberdeen-led NWPVD release having resistance/tolerance to both tuber necrotic viruses is Pomerelle Russet (Stark et al., 2018), with Payette Russet, a 2015 NWPVD release, also has moderate resistance to corky ringspot (CR) disease, whereas standard varieties are considered susceptible (Novy et al., 2017). In addition, the Aberdeen breeding program is progressing in the evaluation and identification of germplasm with genetic resistances to potato viruses X and Y (PVX, PVY), Potato leafroll virus (PLRV), late blight (foliar and tuber), potato cyst nematodes (Whitworth et al., 2014 and 2018; Dandurand et al., 2019), Verticillium wilt (VW), zebra chip and potato psyllid (the insect vector for Liberibacter responsible for zebra chip) (Prager et al., 2022). Payette Russet is an example of our efforts in breeding for extreme virus resistance to all PVY strains (conferred by the Rysto gene). Additionally, Payette has resistance to late blight and common scab, and is moderately resistant to VW, early blight, and CR. In 2014, the Idaho program also began incorporating another unique PVY-resistance gene, Rychc, which confers extreme resistance to PVY from the Japanese breeding clone Saikai 35, via hybridizations. This breeding effort was undertaken to expand the Ry genes present in our program with Ryadg and Rysto-based germplasm and advanced clones already present in most breeding programs, with Rychc utilized more infrequently. Molecular markers for Rychc (Mori et al., 2012) and for Ryadg and Rysto were utilized in the development of a multiplex marker assay (Elison et al., 2020) to expedite the efficiency of breeding for PVY resistance. Its use identified five russet breeding clones in our program having Rychc (in addition to Saikai 35) which previously had not been identified, thereby expediting the development of russet varieties having extreme resistance to PVY (Elison et al., 2021). Research detailing resistance to potato psyllid and Liberibacter (causal agent of Zebra Chip disease) in germplasm from the Aberdeen breeding program has been published (Diaz-Montano et al., 2014; Butler et al., 2011; Wallis et al., 2015; Rashidi et al., 2017; Prager et al., 2018). Further research to explore this unique species-derived germplasm resulted in three additional recent publications (Fife et al., 2020; Vigue et al., 2020; Cruzado et al., 2020) helping to advance efforts in breeding for resistance/tolerance to Zebra Chip disease.
