- Abstract
A field experiment was conducted to evaluate sorghum [Sorghum bicolor (L.) Moench] germplasm lines raised in simple lattice design during the kharif 2020. Genetic variability and character association were studied for thirteen morphological traits viz., days to 50 per cent flowering, days to maturity, plant height, number of leaves, leaf length, leaf width, stem diameter, panicle length, panicle width, panicle weight, test weight, number of primary branches per panicle and seed yield per plant. High heritability coupled with high genetic advance as per cent of mean and high GCV were noticed for plant height, panicle width, panicle weight, test weight, number of primary branches per panicle and seed yield per plant. Seed yield per plant showed a significant positive correlation with number of leaves, leaf width, stem diameter, panicle width, panicle weight, test weight and number of primary branches per panicle. Characters like number of leaves, panicle width, panicle weight and test weight exerted positive direct effect and had a significant positive correlation with seed yield per plant at both genotypic and phenotypic level. So, simple selection based on these characters would be rewarding.
