Abstract

The experiment was conducted with 2 replications and 54 genotypes of wheat consisting 10 lines, 4 testers and their 40 crosses made in line X tester mating fashion in randomized block design during growing seasons 2014-2015. Spike length recorded the highest value of broad sense heritability while Canopy temperature index reported the highest value of genetic advance as a percent of mean and also reported highest phenotypic and genotypic coefficient of variation. Genotypic path analysis revealed that test weight and weight of grain/spike exhibited positive and strong association with grain yield and highest positive direct effects on grain yield. The selection for yield contributing test weight and weight of grain/spike must be given preference along with grain yield for speedy improvement grain yield.
