Assessment of the genetic diversity of the breeding lines and a genome wide association study of three horticultural traits using worldwide cucumber (Cucumis spp.) germplasm collection

Figure S1: Phenotypic standard of fruit stalk-end color. Fruit stalk-end color was scored as 1 to 3 for GWAS. (a): short green shoulder. (b): long green shoulder. (c): whole green body; Figure S2: Association with fruit stalk-end color and spine color. The green horizontal line in the Manhattan plots indicate the significant threshold based on the Bonferroni correction. The position of candidate genes is indicated by blue dotted lines with the names. (a): genome-wide association to fruit stalk-end color. (b): genome-wide association to spine color., Table S1: List of cucumber germplasm collection used in this study (N=264); Table S2: SNP distribution among seven cucumber chromosomes detected by GBS; Table S3: Proportions of Q values in three clusters estimated by STRUCTURE analysis in cucumber germplasm collection; Table S4: List of unit order displayed in the phylogenic tree in this study; Table S5: Significant SNPs and p-values of PM, SDc, and SPc using GBS-GWAS.
