Abstract:
A set of sixty pre-released promising genotypes of wheat were used to study variability, correlation and path coefficient analysis for yield and yield contributing traits in wheat. The high magnitude of genotypic and phenotypic coefficient of variation were observed for ear weight, grain yield/plant, biological yield/plant, peduncle length, sedimentation value, number of effective tillers/plant, number of ear/plant and ear length. High heritability coupled with high genetic advance as percentage of mean was observed for grain yield/plant, biological yield/plant, ear weight, peduncle length and sedimentation value, indicating that heritability may be due to additive gene action and simple selection based on these traits may be effective. Grain yield/plant revealed significant positive association with biological yield/plant, number of effective tillers/plant, ear weight, ear length, number of ear/plant, 1000 grain weight, harvest index and plant height. Hence, improvement of grain yield can be achieved by improving these traits. Biological yield/plant exerted high positive direct effect on grain yield/plant, followed by number of spikelets/spike, harvest index, ear length, number of ear/plant, peduncle length and ear weight. It indicated that these characters had a high association with grain yield/plant and selection for these traits would lead to increase in yield.
