Genetic maps of Lactuca spp. produced by AFLAP. Parental and 235 F6 recombinant inbred lines of an interspecific L. serriola x L. sativa cross were analyzed using genotyping-by-sequencing. The segregation of markers derived from a Armenian999 (L. serriola) and b PI251246 (L. sativa) peaked at approximately 0.5, as expected for an F6 RIL population. c The female genetic map was 1730 cM and contained 3241 Armenian999-derived markers in 1656 genetic bins across nine linkage groups. d The male genetic map was 1705 cM and contained 4947 PI251246-derived markers placed in 2037 genetic bins across nine linkage groups. Unique alignments of e Armenian999-derived markers and f PI251246-derived markers along the nine chromosomes of L. sativa genome demonstrated collinearity with the genome. Because these RILs were predominantly homozygous, a compound map could also be calculated from a combined genotype table (Additional file 3: Figure S2)
