Introduction Hybridization between Phaseolus vulqaris (common bean) and P. acutifolius (tepary bean) is difficult because of reproductive barriers resulting from isolation and specialization (Pratt, 1983). Since tepary carries traits that would be worthwhile in common bean, many breeders have attempted this interspecific cross. The number of interspecific hybrids is usually rather small. Furthermore, the hybrids are mostly cripples, and have low fertility. Recurrent backcrossing has been used… Expand
