Target Audience:The success of an individual cultivar that would come from the efforts during this project, in the seed market is a function of its appeal to seedsmen, growers, shellers, and processors of peanuts. New cultivars often are developed and released in response to the occurrence of new diseases or insect pests, or to address shortcomings of earlier releases as communicated to the breeder by the concerned parties. The breeder must collect extensive performance and quality data on candidates for release, but it is the first year or two a new cultivar is in the hands of the seedsmen that are critical. Being producers themselves, seedsmen must be satisfied as to the agronomic performance of new cultivars before they will risk putting their resources into producing large amounts of seed. As a new release progresses through the seed chain (breeder, foundation, registered, and certified seed production), the seedsmen look at it critically in comparison to the relatively small number of cultivars with which it will compete, often with an eye toward subtle traits that the breeder may have overlooked. Because the seed must be shelled, shellers also get an early look at new releases in shelling plants during this time. The short lifetimes of several released cultivars in the seed market reflect shortcomings that became evident only when they reach the hands of growers and shellers in quantity. In addition to these groups, there are interested parties in peanut cultivars release from this program or based on the efforts from this project. Changes/Problems:

What opportunities for training and professional development has the project provided?One graduate student and one postdoc assisted (and gained knowledge in experimental design) with the field trials, data analysis and PVQE publications. This undoubtedly provided them with the opportunity to grow professionally. In addition, grower trainings were organized during the course of this project in 2021. We organized two in-person field tours, one in general on peanut production at the Tidewater AREC and a second specifically on PVQE research at the Taylor Slade Farm near Williamston, NC. In Sep 2021, two pod blasting clinics were organized in Surry and Windsor, VA to help growers observe and understand maturity, in particular for the most recent released genotypes from the PVQE program; Bailey II, Emery, and Walton, and NC20. How have the results been disseminated to communities of interest?In Jan 2021, PVQE 2020 data were included in two reports published online on the Virginia Cooperative Extension website. In Feb 2021, information was presented to growers, shellers, processors, certified seed producers, and researchers during the Virginia Peanut Production Annual Meeting, which usually counts over 100 attendees. In March, PVQE data was disseminated to the PVQEAC followed on Sep 14 and 21 with two field tours; and, finally, in a series of in-person meetings with farmers in Sep 2021. What do you plan to do during the next reporting period to accomplish the goals?In the 2022 growing cycle, we will repeat PVQE testing across the VC region. Data from the 2021 growing season will be analyzed and published in January and March 2022, and summaries of the reports will be provided in the 2021 NIFA report. In addition, a PVP application and registration article for N.C. 20 peanut cultivar will be submitted.

What was accomplished under these goals?
Growers in Virginia, North Carolina, and South Carolina generally grow Virginia-type cultivars due to suitability to regional environmental conditions and existence of a strong peanut industry tailored to process primarily the large-seeded Virginia-type peanut. These three states represent the VC peanut growing region, and they represent the primary Virginia-type production region in the USA. These three states collaborate through a multistate project, the Peanut Variety Quality Evaluation (PVQE), to evaluate advanced breeding lines and commercial cultivars throughout their production regions. The objectives of this project are: 1) to determine yield, grade, quality, and disease response of commercial cultivars and advanced breeding lines at various locations in Virginia and the Carolinas, 2) develop a database for Virginia-type peanut to allow research-based selection of the best genotypes by growers, industry, and the breeding programs, and 3) to identify the most suited peanut genotypes for various regions that can be developed into commercial varieties. The most recently released cultivars developed as part of the PVQE program and currently grown in the VC region are 'Bailey' (2008), 'Sugg' (2009), 'Titan' (2010), 'Sullivan' (2015), 'Wynne' (2013), 'Emery' (2015), 'Bailey II' (2017), 'Walton' (2019) and 'NC20' (2020). In 2020, PVQE included 30 genotypes: 6 commercial varieties and 24 advanced breeding lines developed by the North Carolina State University (NCSU) and University of Florida/Virginia Tech peanut breeding programs. All breeding lines have 'high oleic' characteristic and they are marked by 'ol' letters in their names. With the exception of Bailey, which is a non-high oleic or conventional cultivar for this trait, all other commercial cultivars used as checks are high oleic. These cultivars include Bailey II, Emery, Sullivan, Walton, and Wynne. As part of this project, genotypes were planted from May 13 through June 10 at five locations in three states: at the Tidewater AREC in Suffolk, VA; Martin Co., NC; the Upper Coastal Plain Research Station (UCPRS) near Rocky Mount, NC; Bladen County, NC; and the Edisto Research and Education Center at Blackville, SC. At Tidewater AREC and Martin Co., NC, two digging dates and two replications within each digging date were planted in a Randomized Complete Block (RCB) design. The first digging date was approximately two weeks earlier than the optimum harvest date (i.e. the second digging date in this test). This setting allows identification of early maturing varieties. At the UCPRS and Bladen County, NC sites only one digging date (optimum) was replicated twice. At the Edisto Research and Education Center, additional region-specific cultivars were employed. For all locations, cultivars were compared with the breeding lines for yield and grading characteristics as the ultimate objective was development of improved Virginia-type peanut cultivars. For objective 1-3, timely results were produced each year. More specifically, yield and farmer-stock grading data included percentage of foreign material (FM), loose shelled kernels (LSK), jumbo and fancy pods, extra-large kernels (ELK), sound mature kernels (SMK), sound splits (SS), other kernels (OK), and damaged kernels (DK). Price per pound was calculated by the federal formula and the crop value per acre obtained as the product of yield times the price per pound. This information was made available to the PVQE Advisory Committee (PVQEAC) comprised of breeders, researchers, growers, shellers, processors, manufacturers, and certified seed producers and distributors in the VC region. Due to COVID-19, the PVQEAC annual meeting was virtual. In this meeting, 'NC20' peanut was presented as a high yielding cultivar with superior resistance to leaf spot disease. To address objective 3, only high oleic breeding lines were included in PVQE testing during the course of this project. 'NC20' is a high oleic cultivar and it was released after the PVQEAC approval by the NCSU. To address objective 4, 12 breeding lines and 2 checks were exposed to soil moisture deprivation for the later part of the growing season using rain exclusion shelters. This test showed that NC20 maintained high yield and percent Fancy pods as well as low DK percent after 4 weeks of low soil moisture stress, at similar levels with the drought tolerant species-derived germplasm line used in this test, 'GP-NC WS17'.

What opportunities for training and professional development has the project provided?The data collected and presented in the official Peanut Variety and Quality Evaluation (PVQE) report has been provided to NCSU, Virginia Tech and Clemsonpeanut extension specialists andNC, VA and SC county extension agents in the Virginia-Carolinas. The data is meant to be a resource for Virginia-type peanut cultivar recommendations for growers, the identification of new peanut breeding lines poised for future release and to compare and contrast lines that would be suitable for growth on each farm, depending on inputs and environmental conditions. How have the results been disseminated to communities of interest?The Peanut Variety and Quality Evaluations (PVQE) are published online each year as a resource for extension specialists, county agents and farmers to evaluate the current cultivars and breeding lines in the NCSU peanut breeding & genetics program pipeline. What do you plan to do during the next reporting period to accomplish the goals?Continue to evaluate additional peanut breeding lines during the stages of development. The lines that are tested in the Peanut Variety and Quality Evaluations (PVQE) are all in different stages of testing. These lines have been initially screened and then more broadly tested in the NCSU peanut breeding & genetics program for three years prior to the evaluations in the PVQE trials. By the end of the PVQE period, if a line has been tested in the PVQE trial for 3+ years (Table 2; Accomplishment Goals), the line would have been evaluated for six years in the NCSU peanut breeding & genetics testing program and would be suitable for release. The ultimate decision would be determined based on a number of addition traits (disease, flavor, pod characteristics) and purification would commence. After this round of PVQE testing, the lines N14002ol and N14023ol wereselected as a candidate for release. This line will be grown in a final purification increase and seed will be provided toNorth Carolina Foundation Seed Producers, Inc. for foundation seed.
