AbstractThree biological races of Erinose (Eriophyes vitis Pgst. sin Colomerus vitis Pgst.) commonly attack vineyards every year. A genetic map Welschriesling x Sirius (Mandl et al. 2006) was used as the basis of QTL (quantitative trait loci) analysis for Erinose. The symptoms were evaluated in five consecutive years in 92 individuals from this segregating population and other OIV traits related to the density of hairs in different tissues were also scored. QTL analysis was performed on all data using Plabqtl version 1.1. A major QTL for Erinose sensitivity was identified and reproducible every year on linkage group 9d close to the SSR marker VMC5c1. Two additional smaller QTLs could also be identified in linkage groups 5 and 17. The fact that some OIV traits related to the density of hairs were linked to the same group of the genetic map, is also discussed.
