Distribution of microsatellite markers on the molecular linkage map of lettuce. The framework linkage map was based on the segregation of alleles in the L. sativa (cv. Salinas) × L. serriola (accession UC96US23) mapping population . EST-SSR markers  are named SML; while genomic SSR markers are named LSSA or LSSB. Scale for the linkage map is indicated on the left side in cM. SSR-based markers are underlined.
