Interpretive Summary:

Technical Abstract: Lettuce (Lactuca sativa L.) production is afflicted 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, changes in growing procedures, and climatic changes. The lettuce breeding, genetics, and physiology project aims to incorporate valuable traits into lettuce cultivars and breeding lines that are adapted to coastal California and low desert production conditions. Information and tools to increase the utility of this germplasm is developed in parallel. This report to the California Leafy Greens Research Program semiannual meeting provides an update on breeding and genetics studies of resistance to lettuce drop, downy mildew, bacterial leaf spot, lettuce dieback, yellow spot malady, and postharvest quality. Results and information are also provided for the effect on silicon nutrition on lettuce yield and quality.
