Breeding populations will be developed by hybridizing high yielding cultivars with sources of resistance to preharvest aflatoxin contamination (1) and sources of resistance to drought (3). These populations will be evaluated under field conditions with drought and heat stress imposed by covering the entire test area with a mobile greenhouse. Aflatoxin contamination of the subsequent yield will be determined using the immunoaffinity column fluorometer method. Progeny will be selected based on relatively low aflatoxin contamination (1) and/or relatively high pod yields (3). 2) Breeding populations will be developed by hybridizing cultivars with high oleic acid with high yielding breeding lines with resistance to the peanut root-knot nematode and tomato spotted wilt virus. These populations will be tested for resistance to nematodes using a greenhouse screening technique. Progenies exhibiting nematode resistance will be field tested for virus resistance, and resulting selections will be analyzed for fatty acid composition. 4) A revised and updated core collection will be used to access genetic diversity for important characteristics for economical productions of biodiesel (pod yield, meat content, percent oil, and disease resistance).
