Mutation breeding is one of the most and uncertain approach of breeding to create desirable genetic variability where other breeding methods are fail to break yield plateau and for the improvement of varieties at plant breeding.
The present study was carried out with 2 Uradbean genotypes WBU108 and KU300 along with control and 16 chemical mutagenic treatments applied with on 14 observable yield attributing traits to assess genetic variability in randomized block design with three replications.
The genotypic genotype WBU108 estimates maximum variability is observed in days to 50% flowering characteristic of 0.4% 5-BU; maximum variability is observed in pod density characteristic of 0.2% EMS and KU300. For WBU108, the best-performing concentration was found in EMS 0.1% (647.33 gm) with the highest yield per plant under lethal dose 50 and for KU 300, the bestperforming concentration was found in EMS 0.1% (666.2 gm).
