Project Type: Trust

Start Date: May 01, 2004
End Date: Apr 30, 2009

Objective:
Determine the adaptability of USDA advanced table grape selections and varieties to the climatic conditions of the grape production region in the Coachella Valley of California. Emphasis will be placed on tolerance of the fruit during development to heat, the uniformity of bud break and flowering with and without Dormex, and timing of maturity based on standard commercial varieties.

Approach:
Seven USDA advanced table grape selections and varieties planted on a standard gable trellis will be evaluated using three treatments. The treatments consist of: 1. the best commercial cultural treatments determined from trials in Fresno; 2. the best commercial cultural treatments plus Dormex; and 3. No cultural treatments, but crop load adjustments will be made to equal those in treatment 1 and 2. Data will be collected to determine: uniformity of bud break and flowering; amount of heat damage on fruit; maturity time in relation to commercial cultivars; color development in red skin grapes; production and fruit quality.
