Location: Crop Diseases, Pests and Genetics Research
Project Number: 2034-21220-008-009-A
Project Type: Cooperative Agreement
Start Date: Jan 1, 2024
End Date: Aug 31, 2024
Objective:
1. Employ marker assisted breeding to develop improved raisin grape varieties with disease resistance, early ripening, and
commercial fruit quality. 2. Develop breeding populations and identify potential markers for naturally dry-on-vine (NDOV) and
fruit shattering traits. 3. Provide samples of advanced raisin grape selections for sensory evaluations.
Approach:
Data on fruit traits such as berry color, field berry weight, seed trace, disease resistance, and presence of the dry-on-the-vine
trait will be obtained through field and laboratory examinations to identify accessions with superior quality. Seeds from
selected plants will be germinated and seedlings will be used for development of markers using phenotyping and genotyping
techniques. Samples of advanced raisin grape selections will be provided for sensory evaluations by the Raisin
Administrative Committee
