Genetic Variability and Character Association Study for Yield Enhancement in Bread Wheat (Triticum aestivum L.)

Abstract

This study was conducted to examine 20 bread wheat genotypes with two checks to investigate genetic parameters, correlations and genetic diversity. This experiment was done in main experimental station of Agricultural Research Farm, Rama University (U.P), Mandhana, Kanpur during Rabi Season, 2020-21 in Randomized Block Design (RBD) with three replications. Analysis of variance showed a very significant difference between the 20 bread wheats of the 11 characters investigated. Genotype HPAN111 showed high grain yields per plant during the control period based on average production. Genotypic coefficient of variation (GCV) was recorded highest for Biological yield per plant (15.073%). Phenotypic Coefficient of Variation (PCV) was recorded highest for Biological yield per plant (16.316%). Environmental coefficient of variation (ECV) was recorded highest for Effective tiller per plant (13.591%). High heritability was observed for most of the traits and it was noted highest for Biological yield per plant (85.4%). Genetic advancement was recorded highest for Biological yield per plant (643.733%). The high Genetic advance as per cent of mean was recorded for Biological yield per plant (28.687%). Grain yield per plant shows Significant Positive Correlation with Biological yield per plant (0.8803**) at genotypic and phenotypic level.
