Forty five F1s and 45 F2s, derived from a 10 × 10 diallel mating design were studied for correlations and path analysis for some components and developmental traits with grain yield in wheat (Triticum aestivum L. em. Thell). Path coefficient analysis revealed that 1,000-kernel weight from component traits and early growth vigour from developmental traits were the only attributes for which selection is effective in both the generations. Separate selection indices based on early flowering and late maturity in F1 and vice-versa in F2 are required to be constructed. The results have been discussed in relation to their implication in the development of better ideotypes in wheat.
