Abstract

Combining ability_for 8 quantitative characters were studied through line x tester analysis involving 11 lines and 4 testers in wheat (Triticum aestivum L.). The estimates of sca variance/gea variance and their ratio (gea variance/sea variance) indicated non-additive type of gene action for yield and most of its components. Among females WH-157 and UP-2338, and among males H9-1981, were found to be the best combiners on the basis of gea effects as well as per se performance. The ranking of hybrids on the basis of per se performance was not reflected in their ranking on the basis of sca effects.
