Interpretive Summary:

Technical Abstract: Development of elite lettuce cultivars is a lengthy process that involves cross-pollination, several rounds of selection, development of homozygous genotypes, and testing of material performance. Use of molecular markers linked to the genes allows for rapid and frequently more accurate selection of desirable genotypes than phenotype-based selection. This marker-assisted selection is used by both public and private lettuce-breeding sectors. Discussed will be progress in linkage mapping, association mapping and marker assisted breeding in lettuce.
