ELABORATION OF ELEMENTS OF METHODS FOR APOMICTIC PROPAGATION OF VALUABLE ACCESSIONS OF WHITE HEAD CABBAGE

Abstract

Exogenous factors affecting on the expression of apomixis in cabbage have been identified. Apomictic seeds developed into embryoids were observed in three cabbage varieties such as Jana, Lazurnaya and Lesia (Ukraine). Thus, it was possible to induce an incomplete organogenesis of parthenogenesis seeds originated from these four varieties of cabbage. The occurrence of apomixis was provoked by the synergitic effect of plant growth regulators and alien pollen applied simultaneously as an aqueous mixture of gibberellins and cytokinin applied on the base of the pistil, while the alien pollen (Chinese radish - Loba) was placed on the stigma of castrated cabbage buds 2-3 days before they disclose.
