Cluster analysis of 37 Chinese pomegranate varieties based on phenotypic traits. Each small square reflects the phenotypic characteristics of pomegranate varieties. The color represents the normalized value, with red representing the larger value and blue representing the lower value. Each row represents the normalized content of different phenotypic characteristics from one variety. Each column represents the difference in the normalized results of different varieties in a single specific phenotype. Seven colors distinguish the seven provinces
