The goal of this project is to create artificial, wild-derived tetraploid peanut species and to improve the efficiency of interspecific hybridization. During the project period, we treated over 1,000 steam cuttings from the crosses between different wild peanuts. We generated three synthetic tetraploid wild peanut accessions that can be directly used to make crosses with cultivated peanuts. We also conducted backcross by using an elite peanut cultivar, TifNV-High 0/L, as the recurrent parent, and the real hybrids were identified by a combination of phenotypic traits and molecular markers. Our efforts provide valuable resource for introgression of disease and pest resistance genes from wild species into cultivated peanuts and will benefit to the peanut community.
