Fig. 10From: Landraces of snake melon, an ancient Middle Eastern crop, reveal extensive morphological and DNA diversity for potential genetic improvementPopulation structure based on allelic frequencies of 2748 biallelic SNP loci among 23 populations. a AMOVA (Analysis of Molecular Variance) based on 2748 loci and 94 individuals from four horticultural types and 23 populations, using the GenAlex program. b Neighbor Joining tree inferred from the SNP allele frequencies using the DIST.GENPOP function in the ADEGENET R package. Nei genetic distances and NJ function were calculated by the APE R package. The four horticultural varieties are marked by color as in Fig. 1Back to article page
