Evaluation of Genetic Variability, Heritability and Genetic Advance in Advanced Breeding Lines of Wheat (Triticum aestivum L)

The Present investigation was carried out using 522 advanced breeding lines of wheat genotypes at BISA Farm, Jabalpur during Rabi, 2018-2019 in randomized block design with two replications. Analysis of variance found the significant difference between breeding lines for all the characters were studied. Appropriate variability was obtainable in the advance breeding lines under study for all the characters indicating sufficient genetic variability among the genotypes. Phenotypic coefficient of variation (PCV) was marginally higher than the respective genotypic coefficient of variation (GCV) for all the characters indicating thereby that there is negligible influence on the characters by the environment. GCV was high for grain yield per plant, grain weight per spike, biological yield per plant, number of grains per spike and number of effective tillers per plant. High PCV was observed for grain weight per spike followed by grain weight per plant, biological yield per plant, number of grains per spike, number of effective tillers per plant and length of main spike. High broad sense heritability along with high genetic advance as percentage of mean were obtained for number of non extruded anther per spike, anther extrusion %, visual score of anther extrusion, biomass per plot and number of productive tillers per plant.
