Use of molecular markers for genotype determination of the ogura rf gene in brassica napus

摘要

This invention relates to Brassica plants and methods of breeding Brassica plants. More particularly, the invention relates to the use of molecular markers for determining the genotype of the Ogura Rf gene in Brassica plants at an early stage in their development. The method involves using a combination of primers derived from RAPD markers in PCR reactions to allow discrimination between homozygous, heterozygous and non-restorer or sterile genotypes. Also disclosed are combinations of primers which allow such discrimination.
