Summary Interspecific crossability among four species of Vigna, namely, V. radiata (mungbean),V. mungo (black gram), V. umbellata (rice bean) and V. angularis (adzuki bean), was investigated. Pod-set and percentages of pods harvested varied with the combinations of two parental cultivars of each species for most of the interspecific hybrid crosses. The use of intraspecific hybrids as parents was slightly superior to cultivars for interspecific hybridization. A remarkable increase in viable seed production was found for the interspecific cross,V. radiata x V. umbellata, by using intraspecific hybrid as parents. Furthermore, a successful interspecific hybrid of V. mungo x V. angularis was accomplished through the use of intraspecific hybrid parents. Reciprocal cross differences were common in all the interspecific combinations. Except for the cross between V. umbellata and V. angularis, all other reciprocal interspecific crosses were unsuccessful. Viable seeds were obtained from the interspecific crosses of V. radiata x V. mungo, V. radiata x V. umbellata and V. mungo x V. angularis. Hybrid plants were obtained from cultured embryos for the interspecific crosses of V. radiata x V. angularis, V. umbellata x V. angularis and V. angularis x V. umbellata. The reciprocal hybrid of the interspecific cross between V. umbellata and V. angularis was successfully made for the first reported time. Growth and lethality of the interspecific hybrid seedlings were influenced by the genotypes of both parental species. Parental genotypes also affected the fertility of interspecific hybrids. Complete hybrid sterility was found in the interspecific crosses of V. radiata x V. umbellata, V. radiata x V. angularis and V. mungo x V. angularis; while reduced fertility was observed for the interspecific hybrids of V. radiata x V. mungo, V. umbellata x V. angularis and V. angularis x V. umbellata.
