Abstract:
The material comprised of total 60 mutants lines and three local checks and one national check of rabi sorghum were evaluated for correlation coefficient and path analysis studies in complete randomized block design with two replications during rabi season of 2020-21 under at Research Farm, Department of Agricultural Botany, College of Agriculture, VNMKV, Parbahni (M.S.). This study aims to analyze and determine the traits having greater interrelationship with grain yield for production of high yielding mutants rabi sorghum genotypes. Results revealed grain yield per plant had positive significant correlation with plant height (0.7439), stem girth (0.6249), panicle length (0.7333), panicle breadth (0.432), panicle weight (0.9577), fodder yield per plant (0.6752), biological yield per plant (0.8591) at genotypic level. At phenotypic level, plant height (0.5402), stem girth (0.4085), panicle length (0.5082), panicle breadth (0.2978), panicle weight (0.8635), fodder yield per plant (0.5027), biological yield per plant (0.7329), zinc content (0.2045) exhibited positive association with grain yield. Four characters exhibited positive direct effect on grain yield per plant at both phenotypic as well as genotypic level, leaf area (G= 0.098, P= 0.225) had highest direct effect on grain yield, followed by internodal length (G=0.211, P=0.544), panicle length (G=0.314, P=1.090), panicle weight (G=0.450, P=2.769), had highest direct effect on grain yield.
