Fig. 6: Canonical correspondence analysis (CCA) plot.

Correlation matrix calculated using dataset of 371 plum accessions genotyped for 24,978 nuclear SNP markers (unconstrained axis). Constrained ordination was done along the CCA1 axis reflecting cp haplotypes C/T (no missing values allowed). P ≤ 0.001 (n = 999). Color indicated cp haplotype C (blue) and T (red)
