The present investigation was studied in fourteen inbred lines of kharif sorghum (Sorghum bicolor L. Moench) hybrids. The experiment was laid out in randomized block design with three replications at Sorghum Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif 2021. Fifteen yield contributing traits were evaluated for correlation and path analysis studies in fourteen genotypes. In present investigation there is existence of higher genotypic correlation when compared to phenotypic correlation that indicates the presence of inherent association among the characters. Significant and positive association was observed between grain yield and its yield contributing traits like stem dry weight, relative water content, SPAD, total chlorophyll content , fodder yield and harvest index at both genotypic and phenotypic level. In this investigation path analysis revealed at both genotypic and phenotypic level for plant height, leaf dry weight, relative water content, SPAD, total chlorophyll content, grain no per panicle, fodder yield and harvest index exhibited positive direct effect on grain yield there by it would play an important role in selection criteria for improving the character grain yield. Among the fourteen genotypes studied inbred lines viz. SPV 2504, CSV 27, CSV 31, CSV 39 and PVK 1025 recorded better performance and these are considered as the superior genotypes.
