Abstract: Mutation was induced in sorghum cultivar ‘PVK 801’ with the help of gamma rays and EMS. 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 were evaluated for correlation and path analysis for the grain yield and some of the independent traits in M2 generation. All these treatments were grown in randomized block design with three replications during Kharif 2019. The correlation studies revealed that positive and significant genotypic and phenotypic correlation of grain yield per plant with number of primaries per panicle, flag leaf area and 100 seed weight. The characters exerted direct positive effect on grain yield per plant with days to panicle initiation, days to maturity, plant height (cm), number of primaries per panicle, panicle length (cm), panicle width (cm) and 100 seed weight. Hence these traits can be considered as selection indices for sorghum improvement programme. The component of residual effect of path analysis was 0.4298.
