This research examines genetic diversity, trait associations, and yield performance in biofortified sweet potato genotypes.
Evaluated twenty biofortified short-duration sweet potato genotypes
Used a randomized complete block design with three replications
Applied ANOVA, correlation, PCA, and cluster analysis to analyze data
Significant genotypic differences were found for various traits (p < 0.001)
Genotype BAU Sweetpotato-5 achieved the highest yield of 44.8 t ha⁻¹
Yield positively correlated with root number and mass
79% of variation described by the first five components in PCA
Cluster analysis identified four distinct genotypic clusters
