PRODUCTION OF SELF-COMPATIBLE BRASSICA HYBRIDS USING A SELF-INCOMPATIBLE POLLINATION CONTROL SYSTEM

摘要

This invention relates to cells of a self-compatible hybrid plant, the parents of which are a homozygous self-incompatible female parent, and a homozygous male parent, and the nuclear genome of which contains a vector comprising a DNA sequence which, when expressed in a plant cell, imparts self-incompatibility to the plant, and a promoter capable of directing the expression of the DNA sequence in the cell. The invention includes the vector, a plant comprising the cells, a plant transformed with the vector, the seed of such plants, and a method for conferring the self-compatible phenotype on progeny of the self-incompatible female parent and self-compatible male parent. The invention comprises an improved self-pollination control system for hybrid seed production or breeding which, by using a knockout transgene to eliminate the self-incompatibility phenotype in hybrids, can result in increased yields.
