This study aims to evaluate genetic variation and selection potential for growth and yield traits in wheat genotypes under optimal and heat stress conditions.
Field research conducted over two years in distinct locations with wheat genotypes.
Randomized Block Design used for field traits and Completely Randomized Design for laboratory assessments.
Analysis of variance performed for sixteen field traits and ten laboratory traits.
Correlation and path coefficient analyses conducted to assess trait contributions to grain yield.
Genetic divergence determined to classify genotypes into groups based on traits.
Significant genetic variability found among genotypes for both field and laboratory traits (P < 0.01).
High heritability and genetic advance observed for critical traits under optimal and heat stress conditions.
Biological yield and test weight identified as significant positive contributors to grain yield under optimal conditions.
Increased importance of spike components under heat stress, affecting overall yield.
Potential heat-tolerant genotypes identified, including HD 2307 and PBW 677.
