1 Breeding SHB Cultivars at UF-IFAS Dr. Jim Olmstead Horticultural Sciences Department FBGA Fall Meeting – September 19, 2013

2 UF Blueberry Breeding History 1950s: Ralph Sharpe begins blueberry breeding at UF 1976: Wayne Sherman and Ralph Sharpe release ‘Sharpblue’ and ‘Flordablue’ – first southern highbush varieties 1990s: Plantings increased with improved varieties released by Paul Lyrene. 2000s: Rapid expansion of Florida industry

3 UF Blueberry Breeding Strategy Recurrent selection High density nursery, rapid breeding cycles Large parent, cross, and seedling numbers

4 Year

5 Up to 200 crosses per year Elite parents (cultivars and advanced selections) Top seedling performers Wild germplasm

28 UF Variety Release Must adhere to current UF-IFAS standards -Tested in enough replication, locations, years, etc. -Chain of custody – developmental timeline, MTA agreements -Foundation stock -Plan for intellectual property protection and commercialization

29 UF Variety Release Cultivar Release Advisory Committee -Departmental, comprised of research and Extension Cultivar Release Committee -IFAS Once the variety is approved by these two committees it is considered “Released”. Variety is commercially available only when licenses for propagation have been offered.

30 Year 13

31 UF Variety Release After release, Florida Foundation Seed Producers, Inc. handles commercialization for the University of Florida. Patent/trademark application filed Licensing strategy developed Licenses for propagation in Southeastern U.S. offered Upon request for other territories worldwide, Invitation to Negotiate (ITN) is considered

32 Royalties UF – IFAS policy on release, protection and introduction of plant material: 70% of the royalty payment comes directly back to the breeding program Royalty payments fund personnel, students, and infrastructure
