Brief Summary of Minutes of Annual Meeting

A large and highly diverse set of plant germplasm was preserved and distributed to scientists, educators, and plant breeders. A total of 102,245 accessions of 1602 plant species representing 25 genera were maintained in the Griffin plant genetic resources collection. Over 86% of these accessions were available for distribution to users and over 94.5% were backed up for security at a second location. A total of 16,275 seed and clonal accessions were distributed upon request to scientists and educators worldwide between October 1, 2020 and July 14, 2021. Sorghum, cowpea, watermelon, and sesame were the most distributed crops. Clonal collections were continually maintained and distributed to stakeholders. Clonal collections include warm-season grasses, bamboo, Chinese water chestnut, perennial peanut, and sweet potato. Preservation methods include tissue culture, field plots, greenhouse plants, and hydroponics. Fifteen accessions of sweet potato were sent to USDA-ARS, Fort Collins, CO for cryopreservation. These activities ensure that the crop genetic resources at the Griffin location are safeguarded for future use to develop new cultivars and identify novel traits and uses in our food and fiber crops.

Although on site regeneration were greatly reduced at the beginning of 2020, late season plantings and collaborator regenerations led to successful regeneration of many crops including wild peanut (Griffin, GA), sorghum and millet (USDA-ARS, Puerto Rico) and vegetable crops (USDA,ARS, Parlier, CA; Rijk Zwaan; Vilmoran; HM Clause; Curry Seed and Chile Company and the World Vegetable Center). This season, regenerations planted include vegetables (605), peanut (639), miscellaneous crops (11), industrial crops (52), legumes (47), clover (26), grasses (39) and okra (70). Of these, 86 wild peanuts (35 different species) were planted in the greenhouses for replenishment of fresh seeds while 435 cultivated peanuts and 154 cowpeas were planted in field plots for regenerations Georgia. Another 50 cowpeas were sent for regeneration in St. Croix.

A collaborative research project with Texas and A&M University and Texas Tech University on drought tolerance in peanut was completed. Over two crop seasons, twelve interspecific hybrid derived germplasm lines from the national peanut collection along with three peanut cultivars as controls were evaluated under a rainout shelter for drought in Griffin. None of them performed better than the cultivated control peanuts for overall drought tolerance. New funding was obtained from the National Plant Disease Recovery System for a collaborative project with the University of Georgia-Tifton to develop molecular diagnostic tools for the detection of peanut clump virus and the Indian peanut clump virus. These diagnostic tools are needed to screen new peanut germplasm entering the country. With partial support from the National Peanut Board, a new collaborative research project was initiated with USDA, ARS, Stoneville, MS, bioinformatics laboratory and the Hudson Alpha Institute, Huntsville, AL, to analyze the wild peanut genome. Increased knowledge of the wild peanut genome will enable peanut breeders to more efficiently cross wild peanut with cultivated peanut. This allows new peanut varieties to be developed with desirable traits originally found in the wild peanut.

Collaboration continues with USDA,ARS, Charleston, SC to cross wild species related to watermelon with cultivated watermelon species. Wild species provide a unique source of important traits for introduction into cultivated crop species. Large portions of the pepper collection were screened for the presence of Tobamoviruses (ToBRFV) and pospiviroids. The presence of viruses or the lack of knowledge concerning the presence or absence of viruses in germplasm hinders the ability to distribute germplasm and can result in the unintentional distribution of plant pathogens. Collaborative studies continue with Baylor College of Medicine to use Next Genome Sequencing to define genetic relationships in pepper and to examine evolution in wild pepper species. Information gained will help plant breeders more efficiently make crosses between cultivated and wild pepper with hopes of bringing new traits into the crop. Collaborative efforts to identify and characterize novel uses of capsinoids in pepper are on- going. Capsinoids, the substance that gives peppers their hot pungent flavor, has been shown to be an important nutraceutical compound with many potential health benefits.

A nutraceutical and health forage evaluation of several Desmodium species was completed in collaboration with Ft. Valley State University. Crude protein levels averaged 23% in two Desmodium species and all Desmodium species had in vitro true digestibility ranging from 80-87%. There were species differences in flavonoid content and high protein precipitable phenolics as well as high total phenolics in one of the species. This encourages the potential use of these Desmoidum species for nutraceutical livestock forages.

In collaboration with Tuskegee University, 580 individual peanut seeds were analyzed for fatty acid composition. The overall project goal is to develop genetic tools for peanut breeders to increase the level of the healthy fat, oleic acid, in peanut seeds. With University of Florida collaborators, six peanut lines were measured for protein content as the first step to identify genes for nitrogen-fixation by peanut root nodulation. In collaboration with USDA-ARS, Tifton, GA, 23 breeding lines were analyzed for fatty acid composition. The aim of the project is to develop new peanut cultivars with both improved disease resistance and seed nutrition quality. A total of 50 peanut samples were measured for protein content, oil content, fatty acid composition, and sugar content as part of a joint seed sprout project with the University of Georgia. The goal of the project is to develop peanut varieties with improved nutritional properties in sprouted product used for human consumption. Additionally, 18 germplasm accessions (3 accessions x 6 botanical varieties) were planted for two years (2019 and 2020) with two replicates. Protein content, oil content and fatty acid composition were measured in these samples. Flavor components will also be measured. The goal is to detect genetic variation in flavors among the botanical varieties and provide useful genetic materials to breeders for development of peanut varieties.
