Studies on genetic parameters in induced micro-mutation population of aromatic rice (Oryza Sativa L.) in M2 and M3 generations

Abstract

An attempt has been made to study the genetic parameters of rice to develop the selection criteria for improving the traits under study. In general, combined treatments showed higher magnitude of heritability and genetic advance as compared to single treatments in both the generations in both the aromatic rice genotypes. A large number of promising families were isolated from M2 population, most of them performed well in M3 generation. The values of GCV, PCV heritability (in broad sense) and genetic advance were high for most of the traits in both the varieties in the combination treatment of 40kR gamma-ray + EMS in both the generations.
