Abstract:
The primary goals of wheat breeding program are to develop new wheat varieties with increased yields. In order to suggest efficient wheat breeding strategies, researchers need information on genetic variations, heritability, genetic progress, and correlation and path analysis for numerous factors. This research study was executed in Lovely Professional University by Department of Genetics and Plant Breeding, Phagwara, India during rabi season 2022-2023. There were 107 genotypes including 4 checks and 103 F5 segregating populations of three crosses were evaluated in augmented design. Analysis of variance showed significant in all the traits except ear weight, 1000 grain weight and chlorophyll index in test versus check. Analysis of variance for test showed significant for all traits except chlorophyll index. High heritability with genetic advance mean was observed for ear length (93.67% and 42.21%), 1000 grain weight (83.67% and 36.53%), grain yield plant^-1 (92.12% and 48.35%), biological yield plant^-1 (95.08% and 60.75%), harvest index (98.17% and 71.59%) and chlorophyll index (96.66% and 70.73%). Number of productive tillers, ear length, number of spikelet’s ear^-1, biological yield plant^-1 and harvest index had positive correlation coefficient and path analysis on grain yield plant^-1. This suggests that selecting for these features may be beneficial in optimizing grain production.
