This study presents a multivariate analysis of phenological traits in vegetable bean (Phaseolus vulgaris L.) genotypes. The research was conducted during 2023–2025 using principal component analysis (PCA) and hierarchical cluster analysis. The results showed that the first two principal components explained the majority of total variation and enabled clear differentiation of genotypes. Based on cluster analysis, the genotypes were grouped into early-, medium-, and late-maturing types. The most influential traits contributing to differentiation were the total vegetation period and biological maturity duration. These findings can be effectively applied in breeding programs for the selection of promising genotypes.
