Tailoring Variability for Yield and Quality Traits in Bread Wheat (Triticum aestivum L.)

Abstract

The present research was carried out at the Breeder Seed Production Unit, JNKVV, Jabalpur, Madhya Pradesh using twenty-one sets of bread wheat genotypes. These were sown and evaluated under the timely sown condition in a randomized complete block design with three replication during post-rainy season 2021- In the present investigation thirteen morphological and one biochemical trait were analyzed. The analysis of variance indicated the occurrence of significant variation among the genotypes for all the traits. The present results indicate that the estimates of PCV were in general slightly elevated than their corresponding GCV for most of the traits studies which indicated that the variability for these traits in the genotypes was not much affected by the environments for the expression of these traits. High heritability with high genetic advance was observed for flag leaf length, grains yield per plant, biological yield per plant, and tiller per plant, and high heritability (narrow sense) coupled with the moderate genetic advance in percent of mean was observed for flag leaf width, grains per spike, plant height, and spikelet per spike. It can be summarized that constructive variability in parents and progenies was developed through hybridization which can be appropriately utilized for the selection of suitable genotypes to obtain high protein and high yield potential in bread wheat.
