Interpretive Summary:

Technical Abstract: Lettuce production is beset by numerous biotic an 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 lettuce 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 mid-year meeting provides an update on studies of postharvest quality of lettuce and host plant resistance research effort that includes resistances to corky root, Fusarium wilt, leafminer, lettuce aphid, lettuce drop, tipburn, Verticillium wilt, bacterial leaf spot, downy mildew of lettuce, and Impatiens necrotic spot virus, and the detection of lettuce downy mildew.
