QTL Mapping of Alpha Acid Content in Hop
Effects of quantitative trait loci (QTLs) and the map locations were determined for alpha-acid content in hop (Humulus lupulus L.) using amplified fragment length polymorphism (AFLP) and microsatellite markers (SSRs). Genetic linkage maps were constructed from mapping population consisted of 111 progeny from a double pseudo-testcross. A total of 194 markers (150 AFLPs, 43 SSRs, 1 hypothetical sex marker) were located on the 20 linkage groups (LGs) of the maternal and paternal maps, covering total map lengths of 706 and 616 cM, respectively, due to the presence of 16 common biparental SSR markers the homology of seven LGs between parental maps could be inferred. The progeny segregated quantitatively for alpha-acid content determined in the years from 2002 - 2006. Thirteen putative QTLs were identified on both maps. Possible homologies between QTLs for alpha-acid content detected in different years as well as in both maps could be established in at least three chromosomal regions. Previously reported genetic map was successfully saturated with additional SSR markers providing a practical tool for the development of marker-assisted selection programme in hop.
