Correlations between the evaluated descriptors and individuals in a given population (P). (A) Scatter diagram showing the distribution of selected characteristics in the H. ‘Red Cauli’ population in the space of the first two axes. The first two axes explain 26.02% and 23.84% of the total variability, respectively. (B) Diagram of component weights showing the correlation of selected characteristics in the H. ‘Red Cauli’ population. The first two axes explain 26.02% and 23.84% of the total variability, respectively. (C) Scatter diagram showing the distribution of selected characteristics in the H. ‘Xenox’ population in the space of the first two axes. The first two axes explain 28.92% and 22.62% of the total variability, respectively. (D) Diagram of component weights showing the correlation of selected characteristics in the H. ‘Xenox’ population. The first two axes explain 28.92% and 22.62% of the total variability, respectively. (E) Scatter diagram showing the distribution of selected characteristics in the H. ‘Purple Emperor’ population in the space of the first two axes. The first two axes explain 30.60% and 19.43% of the total variability, respectively.
