Discussion

Analysis shows genetic variability for grain yield in maize genotypes, suggesting potential breeding approaches.

Grain yield and agro-morphological traits showed significant genetic variability among the maize genotypes evaluated.
Genotypes displayed a low heritability estimate, indicating a limited response to selection based on the traits assessed.
Principal component analysis revealed major contributors to variability, primarily focusing on grain yield and morphological traits.
Cluster analysis identified four distinct groups, enabling selection of diverse genotypes for enhanced crop breeding strategies.

Godonu et al. (2025) studied this question.
