Abstract:
Knowledge of nature and magnitude of genetic variability among genotypes, mutual association between yield and attributing traits is important for effective selection in plant-breeding program. Ninety advanced bread wheat lines along with four standard checks viz. HD-2967, NW-5054, DBW-187 and HD–2733 were evaluated at Main experimental station of Acharya Narendra Dev University of Agriculture and Technology, Ayodhya (U.P.) in augmented block design in Rabi 2020 to evaluate the correlation of yield and yield attributing traits and determine the direct and indirect effects of yield attributing traits on grain yield. Analysis of variance showed significant differences among the tested genotypes for all the majority of agro-morphological characters under study which clearly indicates high variability among the tested advanced bread wheat lines. Grain yield had highly significant and positive correlation with biological yield per plant, harvest index (%), days to maturity, days to 50% flowering, plant height and tillers/plant. Maximum positive direct effect on grain yield per hectare was exerted by biological yield per plant followed harvest index, days to 50% flowering and plant height. Selection based on these traits could be more effective to maximize grain yield. Path analysis showed that maximum positive direct effect on grain yield per hectare was exerted by biological yield per plant followed harvest index, days to 50% flowering and plant height. This implies the true relationship between these traits and grain yield. Consequently, these traits should be considered as important selection criteria in future breeding program for the development high yielding wheat varieties.
