  • Patent number: 5973233
    Abstract: Our invention comprises a gene restorer line of Brassica napus which contains a Raphanus sativus restorer gene but is essentially free of Raphanus sativus genes which produce high glucosinolate. In particular, we provide a gene restorer line, and progeny derived therefrom, seed of which is low in glucosinolates. The Brassica napus restorer lines are free of glucosinolate-producing genes having a characteristic RFLP signature. The method of producing such lines which comprises crossing Brassica napus restorer lines and hybrids with desired Brassica napus germplasm and selecting progeny having a characteristic RFLP signature is also encompassed by the present invention.
