Eggplant (Solanum species) is the most popular and widely cultivated vegetable crop in the tropic and subtropics regions of the globe mainly for its immature fruits and leaves as vegetables. The research study was to access the correlation and to estimate the level or amount of heritability among morphological and mineral traits in S. aethiopicum.
Fifteen accessions were grown in a Randomized Complete Block Design with three replications to determine strength of association among sixteen agronomic and nutritional traits. Pearson Product Correlation was used to estimate the relationships in the study. Days to flowering registered significant positive correlations with height at flowering and fruit length at both phenotypic and genotypic levels. The most striking result was significant negative correlation between number of seeds per fruit and fruit length. Thus suggesting that selection for accessions with long fruits characteristics will lead to reduction in seed content of the fruits. The seed content of the fruits is the main unreasonable factor to the acceptance of garden eggs to the larger consumers in Nigeria.
