Quantitative Analysis of Yield Contributing Traits and Seed Quality Parameters of Wheat(Triticumaestivum L.)
Abstract
In the present investigation 72 exotic and indigenous genotypes of bread wheat along with three checks were evaluate during Rabi season, 2013-14. The experiment was conducted in Augmented Block Design having 8 blocks of plots each at Men Experiment Station farm and seed attributes tested in Seed Testing Laboratory of Seed Technology Section, Narendra Deva University of Agriculture & Technology, Narendra Nagar Kumarganj, Faizabad (U.P.). Highly significant differences were observed among the genotypic for all the seed yield traits. The phenotypic coefficient of variability (PCV) ware close to genotypic coefficient of variability (GCV) for more of the traits which indicate that environmental effect has no considerable effect on the total phenotypic variation. Vigour index showed the highest genotypic coefficient of variation followed by vigour 1000-seed weight, days to maturity and plant height. A highest estimate of both heritability and genetic advance was exerted by 1000-seed weight followed by number of tiller per plant and Vigour index. Heritability and genetic advance indicated that the nature action and reliability or those characters for selection and emerged as ideal traits for improvement through selection.
