Evaluation of advanced generation progenies for resistance to shootfly atherigona soccata in sorghum


, : Evaluation of advanced generation progenies for resistance to shootfly atherigona soccata in sorghum. Indian Journal of Genetics & Plant Breeding 43(2): 291-293

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 (BC) F3 progenies, 1 F3 progeny and 3 F4 progenies were more resistant than the highly resistant parent, IS 5604, suggesting transgressive inheritance of the character. There are 11 (BC) F3's, 2 F3's and 17 F4's superior to commercial variety M 35-1. Broad sense heritability was around 30% indicating greater influence of environment.

In a 2-year field study conducted in New Delhi, India, 11 sorghum germplasms were screened for resistance to Atherigona soccata and Chilo partellus. The entries E 103, E 108, E 109, E 112 and E 358 showed multiple resistance to both pests.
