Advanced generation material was evaluated to estimate the extent of variability, heritability and genetic advance. F3’s were more variable and F4’s the least, for egg count/plant and dead hearts (%). Back cross F3’s were comparatively more resistant. Five (BG) F3 progenies, one F3 progeny and three F4 progenies were more resistant than the highly resistant parent, IS 5604, suggesting transgressive inheritance of the character. There are 11 (BC) F3’s, two F3’s and 17 F4’s superior to commercial variety M 35-1. Broad sense heritability was around 30 per cent indicating greater influence of environment.
