Genetic Variability, Heritability and Genetic Advance in Analysis of Seed Quality Parameters in Wheat (Triticum aestivum L.) Germplasm

The present investigation was carried out using twenty wheat genotypes in a laboratory setting to assess genetic variability, heritability, and genetic advance for seed quality traits. The experiment followed a Completely Randomized Design (CRD) with three replications during 2024–25 at the Department of Seed Science and Technology, Bundelkhand University, Jhansi. Significant genotypic and phenotypic variation was observed for vigour index-I, shoot length, seed width, root length, and seedling length. High heritability coupled with high genetic advance was recorded for shoot length, root length, seed width, and seedling dry weight, indicating additive gene action and suitability of these traits for selection. Vigour index-I ranged from 1540.00 (JK-7254) to 2349.60 (WH-1402), with a mean of 2106.44. The results underline the importance of these traits for breeding high-quality seed varieties in wheat.
