To develop lettuce cultivars and breeding lines with high yield and quality, uniformity and disease, disorder, and insect resistances, including resistance to yellowing viruses, big vein, downy mildew, tipburn, sclerotinia, whitefly species, leafminers. Collect, catalog, maintain, evaluate, and distribute valuable germplasm. Conduct standard and molecular genetic studies.
Approach:
Use hybridization, selection, and molecular techniques to develop desirable new populations. Test cultivars and breeding lines, make appropriate crosses, select within segregating populations, develop series of inbred lines, test under commercial field conditions.
