Fig. 2From: The genetic control of polyacetylenes involved in bitterness of carrots (Daucus carota L.): Identification of QTLs and candidate genes from the plant fatty acid metabolismInterval Mapping’s logarithm of odds (LOD) scores of markers for PA contents and PA ratio (FaDOH/FaOH), shown alongside the nine carrot chromosomal linkage groups. The LOD threshold for significance (p < 0.05) calculated by 5000 permutations is shown as black line. Linkage map is presented in Additional file 3: Fig. S2Back to article page
