Abstract:

Genetic variability was studied in backcross segregating generations of the cross GW322 X Parula in bread wheat during Rabi season of 2015-2016 at AICRP on wheat, MARS, UAS, Dharwad, Karnataka. The study revealed highly significant differences for all the yield and its contributing traits, indicating the presence of high genetic variability. The phenotypic and genotypic co-efficient of variation (PCV and GCV) was high for grain yield per plant followed no of productive tiller per plant and moderate for plant height, spike length and thousand grain weight. High heritability coupled with high GAM was found for the traits viz., plant height, no of productive tiller per plant, spike length, thousand grain weight and grain yield per plant indicating presence of substantial amount of variability for these traits which is key of practicing selection in any breeding programme.
