Evaluation of advanced generation progenies for resistance to shootfly in sorghum

Advanced generation material was evaluated to estimate the extent of variability, heritability and genetic advance. F sub(3)'s were more variable and F sub(4)'s the least, for egg count/plant and dead hearts (%). Back cross F sub(3)'s were comparatively more resistant. Five (BC) F sub...

Zusammenfassung:	Advanced generation material was evaluated to estimate the extent of variability, heritability and genetic advance. F sub(3)'s were more variable and F sub(4)'s the least, for egg count/plant and dead hearts (%). Back cross F sub(3)'s were comparatively more resistant. Five (BC) F sub(3) progenies, one F sub(3) progeny and three F sub(4) progenies were moce resistant than the highly resistant parent, IS 5604, suggesting transgressive inheritance of the cheracter. There are 11 (BC) F sub(3)'s, two F sub(3)'s, two F sub(3)'s and 17 F sub(4)'s superior to commercial variety M 35-1. Broad sense heritability was around 30 per cent indicating greater influence of environment.
