Discussion

Line × tester analysis reveals the role of combining ability and gene action in okra yield components.

Significant mean squares due to line × tester interaction highlight non-additive gene action in okra.
Specific combining ability variances were generally higher than general combining ability variances, showing trait-specific strengths.
Hybridization strategies identified promising parents and hybrids for improving fruit yield in okra, emphasizing heterosis.
The cross 2017/OKYVRES-1 × HRB-108-2 demonstrated superior performance and potential for breeding programs.

Jethva et al. (2025) studied this question.
