Abstract: Sequence-related amplified polymorphism (SRAP) markers were used to construct a draft linkage map using an F1 population (84 individual plants) derived from a cross between PI 651947 and PI 652007; these lines possess different agronomic traits and DAN levels. Draft linkage maps of PI 651947 and PI 652007 were constructed using Map Manager QTX b20 software. 77 markers were used to construct parental linkage maps.The male map included 4 linkage groups with 19 molecular markers covering a total length of 450.9 centimorgans (cM). The average genetic distance between markers was 23.7 cM. The female map included 13 linkage groups with 58 molecular markers and covered a total length of 1404.8 cM. The average genetic distance between markers was 24.2 cM. This information established a foundation for extending genetic mapping in chicory and will serve as a framework for mapping QTLs and provide information required for further molecular studies.
