Thirty interspecific crosses (including reciprocals) involving three genotypes/varieties of greengram (Vigna radiate (L) Wilczek) cv. HUM 1 HUM 2 & HUM 8 and five genotypes/varieties of blackgram (Vigna mungo (L.) Hepper) cv. T 9, Pant U 19, PDU 1, BHUU 1 & BHUU 91-346-1 were attempted. Nine out of 30 crosses were successful only when greengram was used as seed parents. The crossability ranged from 0.0 to 61.0 per cent. Germination, survival and pod bearing habit of the F1s hybrids were much better in Kharif season as compared to spring/summer season.

The efficiency of a breeding programme depends mainly on the direction and magnitude of the association between yield and its components and also the relative importance of each factor involved in contributing to grain yield. The path analysis provides an effective measure of direct and indirect causes of association and depicts the relative importance of each factor involved in contributing to the final product.

Ten genotypes as lines and three genotypes as testers of mungbean were investigated for combining ability analysis through crosses developed into line x tester passion. The study revealed that the gene action involved in controlling traits viz., plant height, number of pods per plant, number of seeds per pod and grain yield per plant was non-additive; while the characters viz., number of branches per plant and 100-grain weight had additive gene action. Genotype KM 2264 was found good general combines for most of the yield attributing traits.
