Research Project: Development of Improved Raisin Grape for Mechanical Harvest Including Types Resistant to Powdery Mildew

Location: Crop Diseases, Pests and Genetics

Project Number: 5302-21220-005-08
Project Type: Trust

Start Date: Aug 01, 2008
End Date: Jul 31, 2013

Objective:
Develop new raisin grape cultivars for mechanical harvest and evaluate existing raisin selections in the breeding program to determine their commercial potential.

Approach:
Standard sexual hybridization will be used to combine traits between seedless raisins and in some instances seeded parents will be used for traits not found in seedless germplasm. Embryo rescue will be used to recover plants from seedless parents. Plants will be evaluated in the field for fruit and vine characteristics. Selected individuals will be put in six vine plots to test production and raisin quality. Cultivars with good raisin quality that ripen early and that can be mechanical harvested will be released to the industry. Documents Trust Agreement with California Raisin Marketing Board. Log 35739.
