Data on 84 genotypes grown in 3 environments were subjected to correlation and path analysis. Seed yield/plant was positively and significantly correlated with number of productive branches/plant, number of capsules/plant, capsule length and number of seeds in 5 capsules. The magnitude of the correlation coefficients and the direct and indirect effects of various yield components on yield varied with environment, suggesting considerable genotype X environment interaction in the expression of the traits. Number of capsules/plant was the most important trait contributing directly and indirectly to seed yield in all environments.
