Abstract

A biparental population segregating for downy mildew resistance was studied to identify resistance linked molecular markers. The progeny of 202 individuals from a cross of V3125 (susceptible breeding line) with 'Börner' (resistant rootstock) was phenotyped in the field in four seasons and by evaluating artificially infected leaf discs. QTL mapping revealed a major resistance locus on chromosome 5 that explained up to 17.4 % of the phenotypic variance. This new resistance locus was named Rpv14. It was transmitted from the male grandparent V. cinerea Arnold to 'Börner' and is associated with the marker GF05-13.
