Description Arachis glabrata Benth, variety glabrata collector GK 10596 (PI276233; ICG 8176) belonging to section Rhizomatosae has resistance to rust, late leaf spot and viral diseases. A. hypogaea L. cv MK 374 (section Arachis) is susceptible to rust, late leaf spot and to the viral diseases peanut stripe, peanut mottle and peanut bud necrosis. Hybrids between A. hypogaea cv MK 374 and A. glabrata were produced after inter specific pollinations and embryo culture. The hybrids produced had morphological characters of both parents plus floral abnormalities not seen in either parent. It was possible to identify the hybrids by esterase isozyme analysis when still in culture. Cytological research showed variable chromosome association and also homeology between the genomes of A. hypogaea and A. glabrata. The hybrids inherited resistance to rust, late leaf spot, peanut bud necrosis and peanut stripe diseases from the pollen parent A. glabrata.
