The values in the column “No. of varieties” and “POD activity” were in turn corresponding to the genotypes in column “Genotype”. “None” indicated no such values were detected in association population. “–” represented the uncertainty or missing values. The lowercase letters a, b, and c indicate significant differences after an analysis of variance (P < 0.05)
¹ Genotypes detected from 20 SNPs significantly associated with POD activity. The two letters represented the SNPs from two alleles, respectively
²The total variety number may not add up to 207 in cases the genotype of some varieties were missing
