영문 초록

Crossability of interspecific hybridization in genus Vigna was measured in all possible combinations between adzuki bean and mung bean as female parents and mung bean, adzuki bean, black gram, rice bean and V.glabrescens as male parents. Incompatibility was found in interspecific hybrids when adzuki bean was crossed as female parent. Immature embryo culture derived from hybrids of adzuki bean×black gram and adzuki bean×V.glabrescens failed to regenerate plants, whereas regenerated plants of adzuki bean×rice bean and adzuki bean×mung bean were completely died at seedling stage after transferring. Some seedling were obtained through embryo culture of mung bean×adzuki bean or mung bean×V.glabrescens, but they were not survived at all. F₁ hybrids were flowering well but sterile in mung bean×rice bean and V.glabrescens×mung bean. Even though mung bean was fairly compatible with black gram, embryo culture was the only way to obtain hybrids. Hybrids were partially fertile and flowering well, but their pod set was low. Normal pollen germination and pollen tube growth were observed in all hybridizations among Vigna species. Mostly, pollen tubes reached ovules within 24 hours after pollination.
