Fig. 5From: Analyzing genetic diversity in luffa and developing a Fusarium wilt-susceptible linked SNP marker through a single plant genome-wide association (sp-GWAS) studyPopulation structure obtained by Structure software from 97 luffa individuals for different values of clusters (K). Population structure was conducted among 97 luffa individuals including 73 accessions by structure software with distinct clusters: (a) K = 2; (b) K = 3; and (c) K = 4. Each individual is represented by a vertical barBack to article page
