Abstract:
The characters correlation and their direct and indirect effects were studied in 47 germplasm lines. The association study revealed the positive and significant correlation with days to 50 per cent flowering (G=0.152*, P=0.123*), Plant height (G=0.231*, P=0.227*), Number of primaries per panicle (G=0.349**, P=0.343**), Number of grains per primary (G=0.303**,P=0.297**), panicle width (G=0.459**, P=0.427**), and Seedling vigour (G=0.132*, P=0.102*) with grain yield per plant. The partition of yield and yield attributes into direct and indirect effects revealed that the characters viz., number of grains per primary (G=0.273, P=0.182), panicle length (G=0.131, P=0.059), panicle width (G=0.624, P=0.437), 100 grain weight (G=0.116, P=0.103), physiological maturity (G=0.051, P=0.007), SPAD value (G=0.075, P=0.041), and seedling vigour (G=0.147, P=0.091), showed a positive direct effect on grain yield per plant. On grain yield indicating the importance of these characters hence, these characters should be considered while planning a breeding strategy by utilizing rabi sorghum.
