Abstract

A total of 80 interspecific crosses i.e., 36 each of V. radiata × V. umbellata (V. radiata as female) and V. mungo × V. umbellata (V. mungo as female) and 08 crosses of V. radiata × V. mungo (V. radiata as female) were attempted to study the crossability relationship among these three Vigna species. Among the crosses of V. radiata × V. umbellata the crossability was observed highest in HUM 12 × RBL 9 (16.27%) followed by HUM 12 × RBL 9 (15.78%). In case of V. mungo × V. umbellata, the maximum crossability of 11.36% was noticed in cross, Mash 338 × RBL 9. For V. radiata × V. mungo, the highest crossability was visualized in hybrid, ML 1464 × Mash 338 (37.5%). The study indicated that different kinds of pre and post fertilization barriers are responsible for complete sterility to low fertility. RBL 1 and RBL 9 gnotypes of ricebean showing substantially high percent of crossability and better seed set with different cultivars of mungbean and blackgram may be utilized for genetic improvement of the mungbean and blackgram.
