Abstract: The experiment was conducted at the Research cum Instructional Farm of S. G. Collage of Agriculture and Research Station Kumhrawand, Jagdalpur, Bastar, IGKV, Raipur. The experiment was conducted during Rabi 2022-23 by using Augmented Randomized Block Design with 10 blocks in which 500 mutant lines including three check varieties. The results of the analysis of variance showed that all the characters that was studied had an average amount of variability. PCV values were found to be slightly higher than GCV values showing the influence of environment on character expression. The highest heritability was found by flag leaf length (20.80%) and the lowest heritability was found by test weight (1.20%). The correlation among traits towards yield revealed the significant positive correlation with number of grains per raceme, test weight and flag leaf width. Number of grains per raceme (0.8437), exhibited positive direct effect on grain yield. Therefore, these traits could be effective for the improvement of yield in successive generations and other breeding programes.
