Analysis of the genetic diversity and structure across a wide range of germplasm reveals prominent gene flow in apple at the European level

Table 2 Descriptive information for each of the three major groups and eight subgroups of genotypes identified by the Bayesian model-based clustering method

	Number of genotypes in the group/subgroup		He	Number of alleles				Allelic richness
Group/Subgroup	Number Genotypes	Frequency of genotypes with qI ≥ 0.8	He	Total	Private	Unique	A	Allelic richness
K1	506	60 %	0.823	307	34	16	19.19	18.63
K2	401	57 %	0.816	287	23	15	17.94	17.76

Summary statistics include the partitioning of number of individuals in each group, expected heterozygosity (He), total, private, unique, and average number of alleles (A). Allelic richness is scaled to the smallest group (K2; N = 401) or subgroup (K1.3; N = 148)
