Abstract

Phytophtora infestans, the causal organism of late blight, is the most important fungal pathogen of potato. In the strategy of potato late blight control utilization of resistant variety is the most important. For creating new resistant varieties Marker Assisted Selection increase significant the efficiency of this process. Genomes of several Solanum species were reported to contain RB homologues with confirmed broad-spectrum defence function. We tested 8 primers for RB gene homologues from Solanum bulbocastanum on different potato species, including S. bulbocastanum, S. demissum, and S. tuberosum. Some primers amplified only S. bulbocastanum, and others amplified olso S. demissum and S. tuberosum.
