Abstract

Genotypic and phenotypic correlations and path coefficient analyses were conducted for grain yield and some biometric traits in 25 cross-combinations of bread wheat under the rainfed conditions. Significant positive geno- typic and phenotypic association was observed between grain yield per plant, and the yield components, such as productive tillers per plant, spike-length, spikelets per spike, grains per spike and 1000-grain weight. The path coeffi- cient analysis revealed that the number of grains per spike and 1000-grain weight had the maximum direct effect on grain yield. These traits may be considered as the selection criteria for developing high yielding wheat genotypes for

rainfed areas.
