Abstract
Lactuca L. is a widely distributed genus of about 100 species. Seventeen species are found in Europe, nine of which are members of the section Lactuca (1). A further 10 species are found in northern America, 33 in eastern Africa and approximately 40 in Asia (2). Lettuce (L. sativa), a diploid with n = 9 chromosomes and a member of the section Lactuca subsection Lactuca, has received most attention. Other relatively well studied species of the same subsection are L. serriola, L. virosa and L. saligna. Although most Lactuca species are self-pollinated (3), some cross-pollination occurs and inter-specific hybrids between different members of the subsection Lactuca can be produced (4).
