Molecular genetic diversity and population structure analyses of rutabaga accessions from Nordic countries as revealed by single nucleotide polymorphism markers

Table 4 Inferred ancestry of 124 rutabaga accessions from Denmark, Finland, Iceland, Norway and Sweden based on membership coefficients

Cluster	Origin of rutabaga^α					Total Number	Ave genetic Distance within subgroup^β
(K)	DNK (23)	FIN (12)	ISL (11)	NOR (28)	SWE (50)	Total Number	Ave genetic Distance within subgroup^β
1^*	21	2	0	8	11	42	0.1805
2	0	0	8	13	4	25	0.4218

Admixture	8.7%	41.7%	27.3%	21.4%	50.0%	33.1%

^α Sample sizes of the Accessions were assigned to a specific cluster (K) if P ≥ 0.70 and those that did not meet this threshold were considered as admixture
Placement of out-groups:*‘Wilhemsburger’ (Germany) = K1 and ^†‘Laurentian’ (Canada) and ^♠ ‘Krasnoselskaya’ (Russia) = Admixture
^βThe average genetic distance within each cluster or subgroup was obtained from the STRUCTURE results
