A genetic map of sugar beet (Beta vulgaris) based on RAPD markers

摘要

AbstractLinkage analysis of sugar beet (Beta vulgarisL.) was performed with random amplified polymorphic DNA (RAPD)‐markers. From three segregating populations, a combined genetic map was constructed which comprises 85 RAPD, five isozyme, one RFLP marker and the genes for resistance against the nematodeHeterodera schachtiiSchm., one restorer locus for male sterility and the genes for annuality and hypocotyl colour. For mapping of the two unlinked restorer genes a statistical model was developed based on the maximum‐likelihood funct
