Analysis of Phenotypic and Genotypic Coefficient of Variance, Heritability and Genetic Advance Estimates in Wheat (Triticum aestivum L.)

Abstract

The present investigation was conducted to estimate the genotypic coefficient of variance (GCV) and phenotypic coefficient of variance (PCV). It was revealed that PCV was higher than GCV. This result indicated less effect of environment on the expression of character studies. High amount of genotypic and phenotypic variation was observed for the characters such as biological yield per plant, Harvest index, number of grain per ear and productive tillers per plant suggesting the presence of large amount of variability. The characters namely, number of grains per ear, 100-grain weight, and number of spikelets per spike showed high amount of heritability. The high amount of heritability indicated that these characters were less influenced by the environment. The characters such as number of grains per ear, 100-grain weight and productive tillers per plant showed both high heritability as well as high genetic advance could be improved through either pure line selection or simple mass selection. Biological yield per plant and number of grain per ear had high GCV, heritability and genetic advance. This indicated that these characters were governed by additive gene effect and can be improved through selection effectively.
