SOME ASPECTS OF SIB PRODUCTION IN F₁ CULTIVARS OF BRASSICA OLERACEA

Sib levels are reported for a wide range of commercial seed crops of Brussels sprout and cabbage hybrid cultivars produced over twelve years in eight countries.
The major source of variation was found to be the inbred used for hybrid production but variation due to crop, year of production and production environment was also significant.
The results are discussed with reference to factors known to affect the level of self-incompatibility and the production of inbreds in F₁ cultivars of Brassica oleracea.
