) accounting for 54.1% of the phenotypic variability in flowering time, but curd or head formation in B. oleracea involves a complex retardation in the juvenile growth phase and flowering time alone may not fully explain or be correlated with commercial

multiple families known to segregate with respect to texture traits would be expected to increase genetic variability relative to phenotypic variability and lack of common ancestry among any of the parental genotypes would increase this effect. The

magnitudes of variance components for yield and nutritional quality traits provide information for better understanding of germplasm properties. Similarly, genotypic and phenotypic variation coefficients (GCV and PCV, respectively) give a measure of the
