Fig. 4From: Landraces of snake melon, an ancient Middle Eastern crop, reveal extensive morphological and DNA diversity for potential genetic improvementDendrogram showing inter-population relationship based on six fruit and leaf morphology traits. Traits were: leaf shape, fruit straightness, fruit color, fruit skin dots, fruit ribs (grooves), fruit length/width ratio. Major clusters represent horticultural varieties with few exceptions. Clustering was performed using Hierarchical cluster analysis (SPSS; see Methods)Back to article page
