Abstract:
The experiment was conducted under rainfed condition at Agricultural Research Station, Madhira during early rabi 2015-16 using 40 ICRISAT sorghum germplasm lines. Estimation of variation, phenotypic and genotypic correlations along with path analysis was calculated for the material under study. Plant height, ear length, straw weight and grain yield showed high genotypic and phenotypic coefficients of variation indicating their high degree of response to environment. Plant height showed positive significant association with days to 50% flowering, days to maturity, number of leaves per plant, leaf length, leaf width, 100 seed weight and grain yield per plant. Number of leaves per plant showed positive significant association with leaf length, leaf width, 100 seed weight and grain yield per plant. Path coefficient analysis revealed plant height exhibited positive direct effect coupled with positive significant correlation with grain yield per plant. Days to 50% flowering exhibited negative direct and negative indirect effects via., days to maturity, number of leaves per plant and leaf length. Number of leaves per plant exhibited positive direct effect as well as positive significant correlation with grain yield per plant.
