Partial least squares discriminant scores plot. (A) Principal component 1 (PC1) and PC2 explained 31.4% and 16.4% of the variation, respectively, indicating Zheng58 × sub-CSSL16 (HY) could be discriminated from Zheng58 × lx9801 (CK). (B) PC1 and PC2 explained 21% and 18.2% of the variation, illustrating the separation between sub-CSSL16 and lx9801. R2X, R2Y, and Q2 refer to the interpretation and predictability values of the partial least squares discriminant analysis models.
