1. Use marker assisted selection in existing segregating populations to rapidly develop high-yielding, high-oleic peanut cultivars. 2. Phenotype and genotype recombinant inbred line (RIL) populations that are segregating for resistance to leaf spot, TSWV, CBR, and white mold to enable the development of additional molecular markers in peanut.
Leaf tissue will be sampled, DNA extracted and analyzed to determine the O/L genotype. The highest yielding high O/L genotypes will be shelled, treated to break dormancy, and sent to the winter nursery for a seed increase. This will provide enough seed to begin replicated agronomic evaluations the following summer. RIL populations that are segregating for economically significant diseases will be phenotyped and genotyped. This will provide data necessary for SNP discovery and genetic mapping of disease resistance QTL and will enable MAS for these traits as well as high O/L in existing breeding populations.
