Abstract
The dominant gene Pvr7 from Capsicum chinense Jacq. ’PI159236’ confers resistance to the pepper mottle potyvirus (PepMoV) Florida (V1182) strain. This gene is tightly linked to the dominant potyvirus resistance gene Pvr4 with observed recombination frequencies of 0.012 to 0.016. A cleaved amplified polymorphic sequence (CAPS) marker linked to Pvr4 was used to localize Pvr4 and, by extension, Pvr7, to linkage group 10 on an interspecific map of pepper. Our results indicated that Pvr4, Pvr7, and Tsw, a gene conferring resistance to tomato spotted wilt virus, comprise the first identified cluster of dominant disease resistance genes in Capsicum L. This position does not correspond to the locations of dominant potyvirus resistance genes in potato or to the positions of any other mapped solanaceous resistance genes or resistance gene homologues.
