Abstract:
In order to investigate the association between various quantitative traits and grain yield per plant, forty sorghum hybrids were assessed including both parents and four checks, viz., CSV 29R, M35-1, SPV 2217 and CSH 13R. The correlation study exhibited positive association of grain yield per plant with panicle weight (0.986), number of seeds per panicle (0.852), panicle width (0.569), hundred seed weight (0.544), number of primaries per panicle (0.282), days to maturity (0.281) and days to 50 percent flowering (0.229). Further, path analysis showed that number of seeds per panicle (0.095), panicle weight (0.081), panicle length (0.052), hundred seed weight (0.017), plant height (0.012) and days to maturity (0.007) exerted high direct effects on grain yield per plant and it also showed lower residual effect which indicated the appropriate selection of characters for the study. From this study, it is observed that panicle weight and number of seeds per panicle made the most contribution to grain yield per plant. As a result, it is suggested to employ these traits as selection criteria for grain yield improvement in rabi sorghum.
