Project Number: 5305-21000-011-08
Project Type: Trust

Start Date: Apr 01, 2004
End Date: Mar 31, 2009

Objective:
Develop landmark cultivars, advanced generation breeding lines and information for use by other breeders. Problems facing the lettuce industry will be addressed using genetic approaches that are suited to coastal, desert, and interior valley locations, to the various types of lettuce, and to the demands of different production and marketing approaches.

Approach:
Evaluate cultivars and PI accessions for useful traits. Plant trials in coastal and desert districts to evaluate yield, head size, and shape, color and various disease, insect, and stress resistances. Look for tipburn, rib blight, pink rib, lettuce chlorosis, and bolting. Continue statewide trials of cultivars and breeding lines. Groups of lines with single or combined resistances will be grown in field trials for evaluation under commercial conditions. Documents Trust with California Lettuce Research Board (#58-5305-4-450).
