Lettuce (Lactuca sativa L.) is one of the most important salad crops worldwide. In Taiwan, lettuce is primarily eaten as a cooked vegetable and has become increasingly popular. Concerning cultivation, lettuce is much less damaged by pests compared with other leafy vegetables; thus, the production has been increasing in recent years. To achieve high yield and good quality, lettuce is also grown in high tunnels, especially for organic production. Batavia lettuce and looseleaf lettuce are the main types grown. Landrace ‘Fu San’, which is adapted to high temperature, high humidity, and varied climate, is the only Batavia lettuce currently being grown in Taiwan. Other foreign commercial cultivars cannot compete with or substitute for ‘Fu San’. However, ‘Fu San’ has two disadvantages: small plant size and slow growth rate. Developing a cultivar superior to ‘Fu San’ would be beneficial to lettuce production not only in Taiwan, but also in other subtropical areas. Single-seed descent (SSD) is a method of plant breeding that has the advantage of obtaining homozygous lines in a much shorter time than conventional plant breeding methods by growing out multiple generations in the same year. The SSD method can be applied to self-fertilized species with high genetic variances for economic characters or crops for which self-fertilization is obligatory for commercial use (Brini, 1966; Fehr, 1987; Macchiavelli and Beaver, 2001). ‘Taoyuan No. 1’ was developed by the SSD method to promote vegetable production in high tunnels. This newly released cultivar with good quality and high yield is described. Origin
