Principle Component Analysis (PCA) to illustrate genotype-based justification for rice accession subgroup clustering based on chilling tolerance phenotypes. PCA was calculated using the 700 K HDRA SNP profiles of 354 Rice Diversity Panel 1 accessions. Green, Cold Tolerant cluster (temperate japonica; tropical japonica, japonica admixes; 205 accessions). Purple, Intermediate Cold Tolerant cluster (aromatic; indica-japonica admixes; 20 accessions). Red, Cold Sensitive cluster (aus, various indica; aus-indica admixes; 129 accessions)
