Q1- and Q2-matrix are significant axes of PCA analyses inferred either from 619 independent DArT haplotypes/markers or from all 1,509 DArT markers, respectively. They represent a fixed co-factor (Q) for population structure. Co-factor K is the genetic similarity matrix. Inflation factors lower than 1.05 are indicated in bold characters
