Phenotypic diversity in mutagenized population of urdbean (Vigna mungo (L.) Hepper)

摘要: Abstract The present study was conducted to assess the extent of induced genetic variability and determine inheritance pattern various yield contributing phenotypic traits in M2 M3 generations urdbean following mutagenesis with single combination treatments gamma rays ethyl methanesulphonate (EMS). mean number seeds per pod 100-seed weight increased all mutagenic both varieties few exceptions generation. Mean length although considerably, however it did not differ significantly most treatments. In generation, 0.2% EMS 300 Gy γ rays+0.2% maximum increase length, varieties. Genetic parameters showed manifold varied from trait trait. Increased for economically important selected mutant lines has successfully contributed diversifying accessible base which could be exploited subsequent improvement through selection.
