Abstract: The present investigation was undertaken on “Study on induced mutations in Kharif sorghum (Sorghum bicolor L.)”. The experimental material comprised of different mutagenic treatments treated with different concentrations viz., 0.1%, 0.2%, 0.3% were EMS treatments and 10 kR + 0.1% EMS, 20 kR + 0.1% EMS, 30 kR + 0.1% EMS and 40 kR + 0.1% EMS were combination treatments and dry and wet control treatments of sorghum cultivar “PVK 801”. All these treatments were grown in randomized block design with three replications during kharif 2019. The genetic variability was significant for yield and yield contributing characters among the M₂ generation. The better mean performance in 20 kR + 0.1% EMS treatment was recorded for most of the characters. The GCV and PCV estimates showed wide variation for most of the characters in segregating M₂ generation. The high GCV, PCV, heritability and GAM were observed for number of grains per primary and grain yield per plant.
