Non Technical Summary
The overall goal of the NC potato breeding project is to develop conventional and specialty-type chip-stock and table-stock potato cultivars that are better adapted to the spring and summer growing conditions of the Mid-Atlantic (M-A) and Southeastern US. Selected clones will have improved yield and culinary and/or processing qualities, and better tolerance to the high temperatures and diseases commonly experienced by potatoes in these regions. The specific objectives of this five-year project are to: 1) continue collaborative breeding projects with the USDA-ARS Beltsville Agricultural Research Center (BARC), the University of Maine, Cornell University, Michigan State University and other potato breeding programs to select and develop new potato varieties with broad adaptation to the eastern US; 2) continue screening efforts focused on evaluating advanced clones from the Cornell, USDA/ARS/BARC, University Of Maine, Michigan State University, and other potato breeding programs for utility in NC and the SE US; and 3) conduct germplasm enhancement and molecular marker studies focused on developing high yielding, high specific gravity potatoes free of IHN. Successful completion of these project goals will: 1) assist breeders in designing regional breeding and selection strategies to more efficiently develop cultivars for wide geographic areas; 2) broaden the germplasm pool of high specific gravity clones available for commercial production in the US; 3) foster increased communication and interaction among potato scientists located in the mid-Atlantic, SE and the NE-1731 Regional Potato Variety Development and Evaluation project; and 4) contribute to the development of a more economically sustainable potato production system in the mid-Atlantic and SE.

Successful completion of these project goals will: 1) assist breeders in designing regional breeding and selection strategies to more efficiently develop cultivars for wide geographic areas; 2) broaden the germplasm pool of high specific gravity clones available for commercial production in the US; 3) foster increased communication and interaction among potato scientists located in the mid-Atlantic, SE and the NE-1731 Regional Potato Variety Development and Evaluation project; and 4) contribute to the development of a more economically sustainable potato production system in the mid-Atlantic and SE.
Project Methods
We will use a combination of traditional, biochemical, and genomics-based breeding techniques as necessary and feasible to facilitate our breeding efforts. We also interact with a wide variety of public and private, and national and international collaborators to achieve our goals.

Progress 10/01/19 to 09/30/20

Outputs
Target Audience:Our target audiences are very broad - ranging from growers and industry personnel seeking highly applied information on new varieties and timely crop production information to multidisciplinary scientists interested in potato genomics and the production of value-added products from potato such as chips and French fries. We adjust our communication strategies appropriately to meet the needs of each target audience and we regularly attend extension-oriented and scientific meetings to disseminate timely information nationally and internationally. Changes/Problems:The pandemic severly impacted our activitied for the 2019-2020 period, however most of our trials were planted on-farm on on the research station before the outbreak and we were able to harvest them. However, direct contact with our farm clientele and out-of-state collaborators was minimal. What opportunities for training and professional development has the project provided?Due to the pandemic no in-person field days were held, but we did produce a series of On-Farm Videos to present research results and one on-line meeting was held that roughly 15 growers attended. The YouTube videos are here: 2020 Potato Field Day Part 1: Table Stock 2020 Potato Field Day Part 2: Table Stock 2020 Potato Field Day Part 3: Chip Trial How have the results been disseminated to communities of interest?See Opportunities for training above. What do you plan to do during the next reporting period to accomplish the goals?This is a continuing project and most if not all of the activities described above will be carried forward, and the results of these trials will be shared with out clientele.

Impacts
What was accomplished under these goals? During 2019 - 2020 we accomplished the following activities. 1. Accomplishment: Under the NE-1731 Regional Potato Variety Development Project we evaluated 220 preliminary and advanced clones in on-farm and research station trials. Impact: The goal of this project is to identify new potato varieties for use in the mid-Atlantic and SE US. Most major varieties, including Atlantic the dominant chipping variety in the US, have passed through this system. 2. Accomplishment: We conducted collaborative early-generation potato selection trials for the Potatoes USA and SNAC International National Chip Processors Trial (NCPT) network. Impact: The NCPT trialing system and database is national in scope and the program is designed to identify and commercialize as rapidly as possible new potato varieties. It has significant grower support and NC State is a key cooperator. 3. Accomplishment: We conducted the 4th year of the Early Generation Southern Selection (EGSS) project designed to rapidly identify and develop new chip-stock varieties adapted to the southern US in collaboration with the NCPT effort. Impact: The EGSS project is designed to identify and commercialize as rapidly as possible new potato varieties for the southern US. It has significant grower support and NCSU is a key member of this project. 4. Accomplishment: We planted 15,768 cycle one clones and selected 1028 clones resulting in a 6.5% selection rate (this includes our single and 3-hill plots, CPB 4-hill plots and single hills from Cornell University). Out of the 928 clones in our cycle two plots (this includes 6-hills, 12-hills and bulk plots), 261 (28.1%) were selected for future evaluation. In the 20-hill, specialty 60-hill plots, and 60-hill plots 138 clones were planted with 34 (24.6%) being selected for further evaluation. Impact: New varieties for the mid-Atlantic and SE US will contribute to a more sustainable and profitable potato industry. 5. Accomplishment: We attended the NE-1731 Project meeting in Beltsville, MD to discuss multi-state potato variety development work in 2020 pre-COVID. Impact: This Regional USDA-NIFA Project is focused on developing new varieties for the eastern US. 6. Accomplishment: NCSU hosted the NE-1731 Project meeting Virtually to discuss multi-state potato variety development work in 2021. Impact: This Regional USDA-NIFA Project is focused on developing new varieties for the eastern US. 7. Accomplishment: We worked with Medius Ag, a leading agricultural database development company, to populate and merge our regional database to their platform. Impact: Medius Ag specializes in database management systems and moving forward will be able to supply a depth of support for development of the utility of the database beyond our capabilities within the potato breeding and genetics program. 8. Accomplishment: Through traditional crossing methods we have introgressed genes associated with Potato Virus Y (PVY) immunity into ca. 40% of our germplasm. Impact: PVY is a devastating virus that can cause up to 80% yield loss in potato, introgression of these R genes contributes to the overall sustainability of the industry by maintaining or increasing yield within current production systems without increased land consumption 9. Accomplishment: We continued to develop and expand our web-based databases for our program and the NE-1731 Regional Potato Variety Development Project. IMPACT: These databases provide web access to variety trialing data for growers, extension agents, and other industry members, and it has become a model variety trial database for the other regional potato projects in the US.
