The present investigation was conducted at the Student Instructional Farm of C.S. Azad University of Agriculture and Technology, Kanpur during the Rabi seasons of 2023–24 and 2024–25 to evaluate genetic variability and traits related to selection in bread wheat (Triticum aestivum L.). The experimental material comprised 181 genotypes16 lines and 5 testers employed in a Line × Tester mating design to generate 80 F? and 80 F? hybrids. A total of 181 entries, encompassing parents and their crosses, were assessed for 16 agronomic and quality traits. Analysis of variance revealed highly significant differences across all characters, demonstrating the existence of substantial genetic variability. Estimates of genotypic and phenotypic coefficients of variation, coupled with heritability and genetic advance, indicated strong potential for improvement, particularly for traits such as chlorophyll content, gluten content, biological yield per plant, number of grains per spike, harvest index, number of total tillers per plant, and grain yield per plant. These traits exhibited high heritability along with high genetic advance, suggesting the predominance of additive gene action and the efficacy of direct selection.
