Technical Abstract: Tomato Spotted Wilt Virus (TSWV) infects over 400 species of plants, including peanut. TSWV is a widespread peanut pathogen in the Southeastern United States causing significant losses to producers in that region. Although not yet a problem to peanut producers in the Southwester United States, TSWV has been found recently in areas of northern Texas and southern Oklahoma. Traditional breeding practices have produced only few TSWV resistant peanut cultivars that are currently available for production. Coat protein-mediated resistance introduced into crops by genetic engineering has offered an alternative method of control of infection by plant viruses. In this study, the nucleocapsid gene of TSWV was introduced into the runner-type peanut Okrun. Results from analysis of both T0 and T1 generations indicate stable incorporation and expression of the TSWV N gene into the cultivar Okrun has been achieved.
