Abstract

A set of 47 SNP (single nucleotide polymorphisms) markers (Cabezas et al. 2011) was tested for their usefulness to improve a genetic map from the cross of GF.GA‑52-42 x 'Solaris' previously established with SSR markers (Schwander et al. 2012). 55.3 % of the SNPs showed informative segregation and 26 SNP markers were localized on 16 of the 19 linkage groups of grapevine. Five chromosome regions with large gaps of recombining SSR markers could be equipped by positioning a SNP marker there. One SNP marker, VV10992, was found linked to the major resistance locus Rpv10 and should be applicable for marker-assisted selection.
