Correlation analysis shows significant yield traits in maize hybrids, highlighting key traits for breeding success.

Ear girth and 100 grain weight show the highest positive correlation with grain yield per plant, indicating critical traits for selection.
Path analysis identifies days to 50% silking as having the strongest direct impact on grain yield, essential for breeding programs.
Randomized block design was used in the analysis of 28 maize hybrids and 8 inbred lines, providing reliable results across replications.
Understanding these traits supports the development of superior hybrids, potentially improving income for farming communities.

Silent Steps (2025) studied this question.
