Origin and Breeding
Controlled pollination: The new variety was hybridised by Lowell Glen Bradford in
1996, germinated and grown as a seedling on its own root in his greenhouse, and upon
reaching dormancy transplanted to a cultivated area of the experimental orchard at
Bradford Farms, Le Grand California. The variety was developed as a first generation
cross using an unnamed plum seedling as the selected seed parent and ‘Black Noble’
plum (USPP 7504) as the selected pollen parent. Subsequent to origination of the new
plum variety it was reproduced by budding and grafting and such reproduction of the
plant and fruit characteristics were true to the original in all respects. Breeder: Lowell
G. Bradford, Le Grand, CA, USA.
