The present study was carried to analyse the EMS induced on seed yield and its contributing characters of blackgram (accession IC-436524) when raised during M3 generation in Kharif season in the month of mid June-mid September, 2022 in the field located Kodad, Suryapet, Telangana. Demand for grain legumes has been increased recently due to their high protein and nutritional values. This resulted for the production of huge quantity of grains to meet the demand for increasing population like India. Genetic variability is prerequisite for isolating high yield blackgram genotypes. Mutation breeding is the simple, cheap and best practise to genetic variability in self pollinated crop like blackgram. In this study, EMS induced blackgram (accession IC-436524) mutants was used to identify the inheritance of high yielding mutants of M2 progeny during M3 generation along with Untreated seeds were used as (Control) and T-9 (as check, collected from ICAR-CRIDA, Hyderabad). Investigation revealed that top 5 mutants with high morphological variations in Plant height, Branches, leaves, Clusters, Pods, Seeds, Seed yield, root length and root nodules were observed. It clearly indicated that there are adequate amount of variability among the blackgram mutants due to EMS treatments.
Blackgram, mutants, M3 generation, Seed yield
Among top five mutants, two mutants from 0.2% and 0.3% EMS viz., I-IC-436524-M3 and IX-IC-436524-M3 showed highest seed yield (g/pl). The % increase calculated for the character seed yield (g/pl) of I-IC-436524-M3 (0.2%) recorded was 97.62 over control (untreated) and 95.82 % over T-9 (check). The % increase calculated for the character seed yield (g/pl) of IX-IC-436524-M3 (0.3%) recorded was 115.40% over control (untreated) and 113.44% over T-9 (check) in M3 generation. Hence these mutants could be utilized for further crop improvement programme in blackgram.
