Description There is no report of successful crosses between cultivated peanut (Arachis hypogaea L.) and wild species from section Procumbentes. Interspecific hybrids between A. hypogaea (section Arachis) and A. chiquitana Krapov., W.C. Gregory & C.E. Simpson (section Procumbentes) were produced by the application of growth regulators to pollinated pistils, and hybrid plants were obtained for the first time by germinating hybrid embryos in vitro. Eleven hybrids were produced, of which one hybrid did not survive to the flowering stage, but the other hybrids were fertile. The hybridity of the F1 plants was confirmed by SSR analysis and one BC1 plant gave rise to mature seeds. In addition, A. chiquitana has been identified as one of the few wild species of Arachis showing resistance to Aspergillus flavus colonization. Aspergillus flavus produces aflatoxin, a carcinogenic agent causing liver cancer, a serious post harvest constraint to peanut production world wide. Initial seed screening of A. chiquitana for A. flavus showed promise of obtaining hybrids resistant to A. flavus colonization, but it is unknown if the interspecific hybrids would also have aflatoxin resistance. This is the first report of obtaining hybrids between A. hypogaea and A. chiquitana
