Estimation of genetic variability, heritability and genetic advance for qualitative and quantitative traits under normal and late sown condition in bread wheat (Triticum aestivum L.)

Abstract

Thirty genotypes were evaluated for genetic variability, heritability and genetic advance under normal and late sown conditions at the research farm of Department of Genetics and Plant Breeding, JNKVV, Jabalpur (M.P.). The experimental material consist of 30 genotype including 5 checks viz., MP 3288, MP3336, MP 3382 GW322 and JW3211. Analysis of observed data showed that mean square due to treatments for all the traits in both the environment were highly significant. GCV and PCV were highest for peduncle length, grain yield per plant, sedimentation value and number of tillers per plant, in late sown condition, peduncle length, number of ear per plant, ear weight, sedimentation value and number of tillers per plant, indicated the presence of sufficient variability in the existing material. The estimate of genetic advance were highest for sedimentation value, peduncle length and grain yield per plant high heritability coupled with high genetic advance as percentage of mean for both normal and late sown condition. This study suggested that the presence of adequate genetic variability, heritability and genetic advance for these traits under normal and late sown environment is suitable for breeding programme and crop improvement. Therefore, selection for such traits may be rewarding.
