Phaseolus lunatus L. is a species with great diversity, which can be explored in breeding programs when adequately characterized. In this work, we evaluated the phenotypic variations of P. lunatus seeds by image analysis using seeds from 13 genotypes from three states: Sergipe (G1, G2, G3, G4, G5, G6, G7, and G8), Bahia (G9 and G10) and Alagoas (G11, G12, and G13). For the analyses, the weight of 100 seeds was estimated, and, in the Groundeye (TBit®), the morphometry by area (mm²), maximum diameter (mm) and minimum diameter (mm), and the descriptors dominant color and RGB color system. The morphometric variables were submitted to variance analysis by the F test, and the means clustered by the Skott-Knott test at 5%. The data were submitted to Pearson correlation analysis (t-Student at 5%), grouped according to dissimilarity by the UPGMA, and represented in the dendrogram. The evaluated characters were submitted to principal component analysis (PCA). Concerning the dominant color, there was a predominance of orange in nine genotypes. As for the RGB color system, G1 presented the highest values and G11 the lowest. G7 was superior for morphometric variables, except for the weight of 100 seeds. There is a positive and signi cant association for morphometry. There are two homogeneous and distinct groups in the dendrogram, and the rst two principal components were responsible for 86.80% of the genotypes' variation. Therefore, applying high-resolution images for phenotypic characteristics of creole bean seeds is a promising nondestructive tool aiming for selection.
