Abstract

Knowledge of genetic and phenotypic association among economic traits helps plant breeders in outlying efficient breeding strategies for development of high yielding wheat variety. An experiment on 238 progenies of wheat along with parents was conducted to determine the correlation and path coefficient analysis of yield and its attributing traits in wheat. The result reveals the presence of high variability among the 238 progenies of wheat. Grain yield per plant had showed high significant and positive correlation with plant height, number of tillers per plant, number of grains per spike, biological yield per plant and harvest index. Further, it indicates that selection based on these traits in breeding programs could be promising in maximizing grain yield per plant in wheat. Whereas, path coefficient analysis depicts maximum direct effect towards grain yield per plant along with biological yield per plant and harvest index.
