PCA biplot showing phenotypic similarity and relationship between genotypes and phenotypic components. a Visualization of quality of representation of variables in top five dimensions. Cos2 is the quality of representation of the variables in the principal component maps. b Biplot analysis for phenotypic similarity. Correlated phenotypic components and genotype samples were located in the same quadrant. The cosine of the angle between vectors indicated correlation between phenotypic components. Highly correlated phenotypic components pointed in roughly the same direction. Nearby points in the biplot represented samples with similar patterns; these were colored according to clustering. The initial letter “Z” indicated that this variable is standardized
