A crossing population was established to characterize quantitative trait loci of agronomically important traits and to elucidate basic principles of quantitative resistance in European type grapevine. Regent (female parent) copes well with fungal attack in field trials, whereas Lemberger (male parent) represents a traditional susceptible cultivar. The progeny comprising 153 individuals segregate for resistance to Plasmopara viticola and Uncinula necator and for other agronomic traits such as onset of berry ripening, bunch- and berry characteristics. Phenotypes were scored repeatedly for these quantitative traits over a period of six years. A dense linkage map of molecular markers (AFLP, RAPD, SSR, CAPS of characterized genes) was established for both parents using Mapmaker and Joinmap software under a high stringency of LOD8. These maps were aligned by anchor markers.
