Hop (Humulus lupulus L.) genetic map and QTL analysis

An F1 population from the cross between the German variety 'Magnum' showing high levels of alpha acids and a wild Slovene male hop '2/1' was employed to develop genetic maps of the parentals based on AFLP and SSR markers and to identify QTLs associated with alpha acid content. The variability of alpha acid content was evaluated in Žalec, Slovenia in the 2002, 2003, and 2004. The maternal map consisted of 90 markers mapped on 13 linkage groups and the paternal map included 70 markers assigned to 12 linkage groups. Four putative QTLs were identified on three linkage groups on the female map. The most promising QTL will be used in Marker-Assisted Selection (MAS) process. The saturation of the map, particularly in the regions of putative QTLs, will be carried out using additional SSR markers. The stability of the QTLs will be tested in next years.
