Abstract

An investigation was undertaken with marrow-stem kale into the relationship between the yield characters of double-cross hybrids and their single-cross hybrid and inbred progenitors.

The number of leaves per plant gave good correlations and demonstrated that selection for this character could be made prior to double-cross hybrid production.

Leaf size and stem yield did not give good correlations and therefore cannot be selected for with useful efficiency.
