Multivariate analysis for head weight and yield performance of experimental cabbage hybrids (Brassica oleracea var. capitata L.)

Abstract

This paper reviews characters of 18 cabbage genotypes (9 experimental hybrids vs 4 cultivars and 5 hybrids from the domestic commercial production). The experimental genotypes differed in head weight, growing season and yield performance. The analysis of variability of the characters was performed by the PCA method. The two characters selected by the scree test accounted for 57.7% of the variability. Based on head weight and yield performance, the tested hybrids were classified into two clusters that differed quantitatively.
