Locating supplementary RFLP markers on barley chromosome 7 and synteny with homoeologous wheat group 5

摘要

AbstractIn order to develop QTL applications, eight new loci were mapped on barley chromosome 7 using 124 doubled haploid lines of the North American Barley Genome Mapping Project (NABGMP) progeny (‘Steptoe’בMorex’)‐ These loci involve six genomic DNA restriction fragment length polymorphisms (RFLPs) and two cDNA‐RFLPs including a puroindoline gene. The distribution of these markers on barley chromosome 7 was compared with that of homoeologous wheat counterparts, i.e. wheat group 5. One locus on chromosome 7 was associated with a QTL for β‐glucanase activity measured in green and finis
