The direct and indirect effects of different quantitative traits on grain yield was studied in 90 hybrids that resulted from ten parents crossed in 10 x 10 diallel fashion. Number of grains per row exerted maximum direct effect on grain yield. Hence the selection for number of grains per row will be highly effective for improvement of grain yield.
