Assessment of genetic variability, heritability and genetic advance in bread wheat (Triticum aestivum L.) Genotypes

The investigation was carried out using 76 bread wheat genotypes including 4 checks at Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur during Rabi, 2019-2020. The experiment was laid out in Augmented Randomised Block Design. Analysis of variance revealed significant difference among the genotypes for most of the characters suggesting sufficient amount of variability in the experimental material under study. High estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were recorded for grain yield per plant, biological yield per plant and sedimentation value indicating the presence of good amount of genetic variability for these traits. High heritability coupled with high genetic gain was observed for grain yield per plant and sedimentation value indicating that all these traits are governed by additive gene action hence the direct selection for these characters may be effective.
