Interpretive Summary:

Technical Abstract: Lettuce and spinach 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 and spinach 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 host plant resistance research effort that includes resistance to corky root, Fusarium wilt, leafminer, lettuce aphid, lettuce drop, tipburn, Verticillium wilt, bacterial leaf spot, and downy mildew of lettuce, resistance to downy mildew, herbicide, and leafminer of spinach, and the detection of spinach and lettuce downy mildew.
