Abstract

Total dry matter production and leaf area index values of sixteen prereleased maize, genotypes were analyzed. MRC 7 with maximum leaf area index of 2.37 and maximum dry matter of 787 g/m 2 showed poor harvest index. MRC 8 and 13 with optimum leaf area index of 1.61 at 75 and 90 DAS respectively showed better partitioning and recorded high seed yield, Hence, optimum leaf area index, better partitioning of dry matter coupled with high seed yield can be taken as the criteria for selection of genotypes.
