Interpretive Summary:

Technical Abstract: Lettuce production is beset by numerous biotic and abiotic challenges, thus the leafy-vegetable industry of California requires continued development of improved, adapted cultivars to meet new disease and insect problems, changes in the market, and changes in growing procedures. The lettuce breeding and genetics projects aim to incorporate valuable traits into crisphead, mixed lettuce, and spring mix cultivars and breeding lines that are adapted to coastal California and low desert production conditions. In parallel, we develop information and tools to increase the utility of our germplasm. This report to the California Leafy Greens Research Program annual meeting provides an update on research effort that includes studies of lettuce resistance to lettuce drop, Verticillium wilt, Fusarium wilt, bacterial leaf spot, downy mildew, Impatiens necrotic spot virus, Pythium wilt, lettuce aphid, tipburn, and abiotic stresses, shelf-life of salad-cut lettuce, horticultural traits and adaptation, and molecular markers.
