Research Project:
DEVELOPMENT OF SEEDLESS GRAPES FOR THE FRESH MARKET, INCLUDING TYPES RESISTANT TO POWDERY MILDEW
Location: Crop Diseases, Pests and Genetics
Project Number: 5302-21220-005-11
Project Type:
Reimbursable
Start Date: Oct 01, 2006
End Date: Jul 14, 2008
Objective:
Develop a series of seedless table grapes that ripen from early to late with white, black & red fruit. Fruit must meet shipping & storage requirements with high quality fruit. Emphasis will be placed on the development of early-ripening white grapes with large berry size, reduced hand thinning in the cluster, good sugar development & attractive appearance. Develop new table grape cultivars resistant to powdery mildew.
Approach:
Standard breeding methods are being used. This consists of selecting varieties having the most desirable characteristics, hybridizing those varieties, selecting the best offspring and testing them as potential varieties. Tissue culture methods will be used to recover hybrids from seedless by seedless crosses. Advanced selections are tested in demonstration plots to determine commercial potential. Major areas of effort are for the development of seedless types to replace seeded varieties and varieties requiring high production costs. Powdery mildew resistance will also be incorporated into the table grapes from resistance germplasm. Selection for resistance will be done in the greenhouse and field where no fungicide applications are made. Documents Reimbursable with the UC Davis. Log 30975. Formerly 5302-21220-004-16R. (8/08).
