Heatmap and hierarchical clustering (double dendrogram) responses to morphological descriptors of Bambara groundnut landraces constructed using ClustVis tools (https://bio.tools/clustvis). The heatmap plot describes the relative abundance of each Bambara groundnut genotypes (columns) within each feature (rows). The color code (blue to dark red) displays the row z-score: red color indicates high abundance, blue color low abundance. The dendrogram shows hierarchical clustering of Bambara groundnut genotypes based on the Euclidian as the measure of distance and Ward’s cluster agglomeration method.
