Sažetak
The effects of quantitative trait loci (QTLs) on quality traits (yield, alpha-acid content) and verticillium wilt resistance in hop (Humulus lupulus L.) were studied using amplified fragment length polymorphism (AFLP) and microsatellite markers (SSRs). A genetic linkage map was constructed from a mapping population consisting of 144 progeny from a double pseudo-testcross. A total of 205 markers were located on the 11 linkage groups (LGs), with 2 LGs located separately on the maternal and paternal maps, covering a total map length of 615 cM. The crossing family segregated quantitatively for alpha-acid content, yield traits and verticillium resistance in 2008 and 2009. Seven putative QTLs were identified on both maps. The reported genetic map provides a good tool for the further development of a marker-assisted selection programme in hop.
