About the Register
Two pomologists at the University of California, Davis, Reid M. Brooks and H.P. Olmo, started gathering information in 1942 for the first list, which included cultivars introduced since 1920, and was published in 1944 in the Proceedings of the American Society for Horticultural Science. The lists have appeared in HortScience since 1969. Pomologists, breeders and extension agents have written, gathered and edited the entries.
Three books collecting previous entries, titled Register of New Fruit and Nut Varieties, were published in 1952, 1972, and 1997, and are now out of print.
The lists have appeared biennially since 2000, and have been known as the Register of New Fruit and Nut Cultivars since List 43 (2006). Ksenija Gasic and David Karp currently edit the Register on behalf of the American Pomological Society and the American Society for Horticultural Science. The most recent article, List 50, appeared in 2020.
To obtain the texts of the entries collected in this database, Julia Stover-Blackburn of the UC Davis Fruit & Nut Research & Information Center scanned The Brooks and Olmo Register of Fruit and Nut Varieties, 3rd ed. (1997); she then ran optical character recognition software on these scans and, as needed, on post-1997 Registers; finally she made the necessary corrections in formatting and spelling, and organized the results. No systematic attempt has been made to update, expand, or correct the information given in the original publications, but in a few cases obvious typos or errors have been fixed. Editors Karp, Preece and Gasic supervised the project.
Dorrie Main and Katheryn Buble of MainLab Bioinformatics, Washington State University designed, posted and maintain the searchable database supported by funding from USDA NIFA National Research Support Project 10.
