This study was conducted on forty-six wood apple (Feronia limonia) accessions planted in a randomized block design to evaluate the genetic diversity, quality traits, antioxidant properties, and nutrient composition. Numerous parameters, such as fruit weight (FW), seed number per fruit (SNF), total soluble solids in pulp of fruit (TSSP), potassium (K), magnesium (Mg), and yield per plant (YP), showed significant heterogeneity in the analysis, suggesting that these qualities could be improved genetically. Both stable and highly variable qualities across accessions were reflected in the coefficient of variation, which varied from 1.94% for root attributes to 132.07% for iron (Fe). To evaluate the possibility of selection in breeding programs, genetic parameters such as genetic and phenotypic coefficients of variation (GCV and PCV), heritability, and genetic advancement were computed. Traits such as FW and SNF exhibited high GCV and heritability, suggesting they are highly heritable and suitable for selection. On the other hand, characteristics such as calcium (Ca) demonstrated low heritability, underscoring the impact of environmental influences. Significant positive and negative correlations were found between several traits using correlation analysis. Fruit length (FL) had strong positive correlations with fruit weight (FW), fruit breadth (FB), and pulp weight (Pu), while iron content (Fe) had negative correlations with many other traits. Seven main components were found using...
