Using joint multivariate analyses of leaf morphology and molecular-genetic markers for taxon identification in three hybridizing European white oak species (Quercus spp.)

Table 2 Proportion of agreement in species assignment of 1369 Quercus individuals using seven different analytical approaches

No.	Approach	2	3	4	5	6	7
1	FAMD/HCPC (all variables)	0.95	0.78	0.85	0.75	0.81	0.87
2	FAMD/HCPC (morphological variables only)		0.74	0.80	0.73	0.76	0.82
3	FAMD/HCPC (genetic variables only)			0.85	0.66	0.88	0.79
4	LDA (all variables)				0.78	0.90	0.85
5	LDA (morphological variables only)					0.69	0.71
6	LDA (genetic variables only)						0.84
7	Structure (genetic data only)

Shown is the congruence among two multivariate analyses (FAMD/HCPC = factor analysis of mixed data with subsequent hierarchical clustering of principal components; LDA = linear discriminant analysis) using three different sets of variables (all, only morphological, only genetic) and a model-based approach (Structure with K = 3) using only genetic data
