Abstract
The study was conducted during the 2019 Kharif with the goals of estimating variability, heritability and genetic advance among all the genotypes in a Randomized Block Design with three replications. Based on variability studies, it could be concluded that the characters viz., plant height (9.93% & 81.81%), leaf width (15.06% & 80.05%), leaf area (10.62% & 81.91%), number of secondary branches (17.29% & 56.59%), total length of primary branches per plant (15.19% & 75.81%), canopy spread (12.81% & 75.33%), length of internodes (13.59% & 79.01%), angle of primary branch (66.32% & 94.01%), all the yield parameters except leaf dry matter content (9.33% & 69.82%) and stem dry matter content (6.82% & 59.22%) and all the chemical parameters had sufficient amount of variability, high heritability respectively. Therefore, simple selection methods will be more effective for improvement of these characters.
