Research Project: "FASTRACK" - A REVOLUTIONARY APPROACH TO LONG-GENERATION CYCLE SPECIALTY CROP BREEDING

Location: Appalachian Fruit Research Laboratory: Innovative Fruit Production, Improvement and Protection

2013 Annual Report


1a.Objectives (from AD-416):
To develop and test a fruit tree rapid-cycling breeding program and to develop novel plum breeding germplasm.


1b.Approach (from AD-416):
Early flowering transgenes will be utilized to develop a rapid-cycling breeding system to dramatically shorten plum generation time. Using this approach, improved plum germplasm with Plum Pox Virus (PPV) resistance and high sugar control will be developed.

"Specialty Crops Research Initiative Proposal"


3.Progress Report:

Combining plum pox virus (PPV) resistance with California germplasm was advanced by one generation. Early flowering, PPV resistance plants were pollinated with California germplasm, and resulting seedlings were planted and screened for both early flowering gene and for the PPV resistance gene. Early flowering, California germplasm was pollinated with pollen from PPV resistant germplasm. Seedlings were germinated and screened for both early flowering gene and for the PPV resistance gene.
