Abstract:
The material comprised of total 24 genotypes and three checks varieties of colored pericarp sorghum were evaluated for correlation coefficient and path analysis studies in complete randomized block design with two replications during Rabi season of 2021-22 under soil moisture deficit condition at VNMKV, Parbhani (M.S.). This study aims to analyze and determine the traits having greater interrelationship with grain yield for production of high yielding Rabi colored pericarp sorghum genotypes with considerable tolerance against soil moisture deficit conditions. Results revealed that leaf area index (G=0.5323, P=0.4693), relative water content (G=0.5395, P=0.4795), SPAD chlorophyll meter reading (G=0.9766, P=0.7235) and fodder yield per plant (G=0.4717, P=0.3982) showed significant and positive association of with grain yield at both genotypic and phenotypic level. Five characters exhibited positive direct effect on grain yield per plant viz. days to 50 percent flowering (G= 0.359, P=0.00), days to physiological maturity (G= 0.255, P= 0.264), seedling vigor (G=0.422, P=0.305), SPAD chlorophyll meter reading (G=1.134, P=1.161) and fodder yield per plant (G=1.645, P=0.718) at both genotypic as well as phenotypic level.
