A genetic map of Bulgarian grapevine cultivar Storgozia based on microsatellite markers was constructed. The F2 mapping population consisted of 98 progeny plants obtained by self-pollination of a newly bred wine variety Storgozia, which possesses field resistance to downy mildew, powdery mildew and grey mould, and tolerance to low temperatures. The population segregates according to disease resistance and a number of morphological characteristics. The genetic map consisted of 92 microsatellite

The order of markers in the constructed linkage map of cultivar Storgozia was consistent with the integrated map of Doligez et al., 2006, with the exception of 5 inversions, each of them containing two adjacent markers. The mapping project aims to develop a framework linkage map for the identification of QTLs for disease resistance and a number of morphological characteristics.
