Table 3 Summary of significant SSR marker-trait pairs from the association test results in the S. oblata populations after correction for multiple testing errors. P value: significance level for association (significance is P < 0.01); Q value: a correction for multiple testing (FDR (Q) < 0.01); R2: percentage of the phenotypic variance explained; a: additive; d: dominance; Sp: standard deviation for the phenotypic trait under consideration. The algorithm and formulas for gene action were calculated as previously reported [36, 37]
