Discussion

Analysis reveals significant trait associations impacting yield in groundnut genotypes, suggesting pathways for genetic enhancement.

Significant variations among groundnut genotypes were observed for all studied traits, indicating potential for improvement.
Kernel yield was found to have the highest positive direct effect on dry pod yield, emphasizing its importance in selection.
Path coefficient analysis highlighted key traits positively associated with yield, such as hundred kernel weight and hundred pod weight.
These findings underscore the need for selecting yield-contributing traits to enhance groundnut productivity and genetic advancement.

Reddy et al. (2025) studied this question.
