Abstract:
A diallel cross study comprising of ten bread wheat (Triticum aestivum L.) cultivars was carried out with parents and F1 progeny to determine genetic variability analysis for yield and its attributes. The result showed that higher estimate of phenotypic and genotypic coefficient of variation for grain yield per plant and biological yield per plant followed by grains per plant, number of leaves per plant, effective tillers per plant, spike per plant, revealed presence of exploitable genetic variance which can be improved through direct selection. Also the above traits reported high heritability coupled with high genetic advance over percentage of mean reporting selection will be rewarding and effective as traits were likely to governed by additive genes. It also provides information on the correlated response to directional selection to predict genetic advancements and so, can be used as selection indices for the functioning of a more efficient selection program. The results obtained from this study might be helpful for wheat breeders trying to make efficient breeding programme to develop new varieties.
