The line x tester design reveals that certain wheat genotypes have superior combining ability, indicating potential for high grain yields.

The hybrid (4×6) showed significant improvement in grain yield across generations, notably reaching 88.01 g per plant in F2.
The general combining ability of parents like Aras was superior for traits including plant height at 90.21 cm and multiple yield metrics.
The significant differences among genotypes suggest targeted breeding can enhance desirable traits in wheat.
The study indicates a promising hybrid (4×6) with superior trait performance, emphasizing the potential for genetic advancements in wheat.
