Abstract:
The characters association and their direct and indirect effects were studied in 68 germplasm lines which are part of minicore. The association study revealed the positive and significant association of days to 50 per cent flowering (0.514**), panicle girth (0.516**), nodes per plant (0.278*), stem girth (0.445**), panicle weight (0.979**), 1000 grain weight (0.768**), seeds per panicle (0.741**), volume (0.714**), grain length (0.353**), grain width (0.639**) and seed thickness (0.643**) with grain yield per plant. The partition of yield and yield attributes into direct and indirect effects revealed that the characters viz., panicle length (0.026), whorls per panicle (0.010), nodes per plant (0.104), plant height (0.021), panicle weight (0.367), 1000 grain weight (0.282), grains per panicle (0.424), volume (0.158), grain density (0.044) and grain thickness (0.033) 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.
