Fig. 3: Single-nucleotide polymorphisms in curly and smooth cultivars.

a The numbers of homozygous (black bars) and total SNPs are indicated; heterozygous SNPs are in gray bars. b The Venn diagram reports the number of SNPs specific to each cultivar or cultivar combinations (overlapping areas); the core-SNPs (see text) that typifies curly from smooth cultivars is in bold. c Genetic relationships among cultivars by concatenated SNPs (neighbor-joining method). Bootstraps values (at the branching points) are given for major nodes and are based on 1000 replicates. The length of the lines indicates the relative distances between nodes
