Vector view of genotype-by-trait principal component analysis (PCA) showing interrelationships among studied variables in anthers excised from freshly cut (a) and cold pre-treated tillers (b). ELS/100A the number of embryo-like structures produced per 100 anthers, R/100ELS the number of regenerated plants per 100 embryo-like structures, GR/100ELS the number of green regenerated plants per 100 embryo-like structures, R/100A the total number of regenerated plants per 100 anthers, GR/100A the number of green regenerated plants per 100 anthers
