Chromosome pairing, pollen and pod fertility in hybrids between cultivated tetraploidArachis hypogaea and 15 synthetic amphidiploids from 8 diploid species (7 of the A genome and 1 of the B genome) of sect.Arachis have been utilized for the identification of putative genome donors in the evolution of cultivatedA. hypogaea. These results, in conjunction with evidence from morphological similarities, phytogeographical distribution and some phytochemical features, confirm the segmental amphidiploid origin ofA. hypogaea. A. batizocoi andA. duranensis are suggested as the donors of the B genome and the A genome respectively.
