Direct and indirect effects of several wheat traits on grain yield
Institute of Field and Vegetable Crops, Novi Sad
Abstract
A detailed analysis of wheat traits has contributed to the greater efficacy of breeding for yield components as opposed to breeding for yield per se. The determination of correlations and direct and indirect effects among wheat traits has made it possible to achieve a better understanding of their interrelationships as well as their better balancing for improved yield per unit area. Forty-four divergent genotypes were analyzed in the paper. Highly significant correlations were found between plant height and spike length, grain number per spike and yield per plant, 1000-grain weight and yield per plant, and spike index and harvest index. Between harvest index and plant height and spike length there was a highly significant negative correlation. Path analysis revealed highly significant direct effects of grain number per spike and 1000-grain weight on grain yield per plant. The observed negative direct effect of spikelet number per spike on plant yield indicates the need to increase spikelet fertility.
