Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. Greenhouse experiments were conducted to identify PVY-immune clones through potato grafting onto virus-infected tobacco plants, determine their genetic constitution for the Ry allele through PCR and evaluate the clones' field performance. Sixty-two clones were identified as PVY-immune through grafting. The SCAR marker allowed the identification of 2 duplex clones for the Ry allele (RyRyryry), which can be used as parents to originate progenies with approximately 80% PVY-immunity in crossings with susceptible clones. Besides, the clones were productive and presented high tuber dry matter content.. |
