The “rancha“ is one of the main diseases in the cultivation of potato (Solanum spp.). It is caused by the oomycete Phytophthora infestans (Mont.) Bary. and its presence is known worldwide for being a very aggressive disease both in the leaves and in tubers unleashing great economic losses. However, over time and with the help of technological advances, its study has been deepened to provide more tools and knowledge about its development. Currently, molecular biology is one of the most important pillars for the discovery of new information and references about P infestans. This work had the purpose of verifying the resistance potential of the great diversity of potatoes native to Peru, for this, 182 accessions from different areas of the country were collected and evaluated at the Institute of Biotechnology -IBT UNALM. We used 6 pairs of primers (named for this study as: Phy12, Phy13, Phy14, Phy15, Phy16 and Phy 17) previously reported in other research associated with ranch tolerance and another 34 new allele-specific initiators additionally designed; all the above under the PCR (Polymerase Chain Reaction) technique. The results were homogeneous in all amplifications. That is, none of the previously selected initiators and the new ones designed were effective in discriminating resistant and susceptible accessions in the germplasm of Peruvian potatoes evaluated, which shows that they must develop their own initiators for the Peruvian potato population since those used have been developed in other potato populations adapted in other latitudes.
