Fig. 2. Linkage groups from the framework linkage map (Zhu, 2002) developed from the cross of Ogle/MAM17-5 (OM), showing significant QTL for oat groat protein and oil content. Molecular markers beginning with the letter "e" are AFLP-type; with "am" or "wisc" are SSR-type; and with others are RFLP-type markers (Zhu and Kaeppler, 2003a).
