Estimating the term…
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.
A method of producing a restorer line of Brassica for use in a cytoplasmic male sterility system, said method including the steps of:
A method of forming Brassica napus hybrid seed and progeny thereof from a cytoplasmic male sterility system which includes a restorer line containing Raphanus sativus restorer gene, the method includes the steps of:
A Brassica napus plant having low glucosinolate seeds containing Raphanus sativus gene material that is capable of restoring fertility to the ogura cytoplasmic male sterile plants, the Brassica napus plant evidencing deficient glucosinolate production from Raphanus sativus which produced low glucosinolate seeds.
A Brassica napus plant containing Raphanus sativus restorer gene unlinked from Raphanus sativus glucosinolate genes adapted to restore fertility to ogura cytoplasmic male sterile plants.
