Abstract

An experiment was performed taking 30 bread wheat (Triticum aestivum L.) genotypes in the experimental area of Wheat Breeding section of DRPCAU, Pusa, Samastipur, Bihar during the Rabi season of 2019-20 to assess the genotypic and phenotypic variance, genotypic and phenotypic coefficient of variability, heritability, and genetic advance as per cent of mean. Observations were documented for fifteen characters. The evaluation was accomplished in Randomized Block Design. Significant differences were revealed by the analysis of variance among the evaluated genotypes for each of the taken parameters. Manipulation by the environment was extremely scanty in the expression of all the traits as it was marked by slight differences between the genotypic and phenotypic coefficient of variation. The characters namely, grain Zn content, grain Fe content, no. of tillers per plant, number of grains/ ear and flag leaf area demonstrated high heritability in addition to high genetic advance as per cent of mean pointing towards that it would be effective to employ simple selection schemes to fetch genetic enhancement in desired track for mentioned characters.

Variance coefficient of variability heritability genetic advance as per cent of mean.
