    • Figure 1. 

      Population structure of the 28 Vitis accessions. (a) Unrooted ML tree. The colors yellow, green, and blue represent the 'Shine Muscat' group, the V. adenoclada group, and the hybrid offspring, respectively. (b) Admixture analysis with K = 2, 3, and 4. (c) PCA results. The correspondence between colors and groups is consistent with Fig. 1a.

    • Figure 2. 

      IBD Relationship among the Vitis accessions.

    • Figure 3. 

      Selective signal detected by XP-EHH analysis. V. adenoclada was taken as the candidate group and 'Shine Muscat' was regarded as the reference.

    • Figure 4. 

      Deleterious mutations analysis among V. adenoclada, 'Shine Muscat', and their one hybrid offspring. (a) The number of heterozygous deleterious alleles. (b) The number of homozygous deleterious alleles. (c) The total number of deleterious SNPs.
