Half diallel analysis reveals significant combining ability and heterosis effects in maize traits, indicating genetic diversity's role.

Significant differences in traits indicate genetic diversity among maize pure lines, emphasizing the role of gene action.
Both general and specific combining abilities showed significant effects, suggesting additive and dominant gene influences on traits.
The dominant gene effects predominated for all traits assessed, with ZP-595 and POL-158 being the best general combiners for grain yield.
Hybrid varieties could be developed from significant crosses, although narrow sense heritability values were low, underscoring trait variability.
