Genetic variability of twenty different genotypes was worked out in two different cropping systems. The investigation revealed that under both the cropping systems, significant differences existed among different genotypes for most of the traits studied. Comparative mean performance of different traits showed significant increase of plant height under intercropping. Seeds per plant, aerial biomass and harvest index showed high heritability estimates under intercropping but moderate under monoculture. Seed yield per plant showed high genetic gain under both the systems. Therefore, it was clear that seed yield per plant was less influenced by the environmental change and the improvement in this trait would be more effective through selection owing to additive gene effects.
