Abstract


Ten parents and 45 F, hybrids of sorghum (Sorghum bicolor (L.) Moench] were studied in rabi season for genotypic correlations and path analysis. Grain yield showed significant positive correlation with panicle breadth, plant height and 100-grain weight in parents, while with panicle breadth, number of leaves and days to flowering in F, s. plant height had the highest positive direct effect on grain yield followed by days to flowering in parents. In F₁s, number of leaves had the highest direct effect followed by panicle breadth and plant height. Though days to flowering showed negative direct effect on yield in Fis, its indirect effect through number of leaves was high, resulting in significant positive genotypic correlation. Improvement in grain yield in rabi sorghum would be possible through selection for plant height, number of leaves and days to flowering.
