Climate change is altering the different ecosystems of various crops, affecting their yield and production. Currently, the native potato is of great importance in Peru, due to its nutritional contribution, the cultural value existing in peasant communities and the genetic diversity it has. Despite this, there is little information regarding the effect that coastal climatic conditions in summer have on the growth and agronomic performance of native potatoes. In the experimental trial, fifty morphotypes of native potatoes were used, which were planted in La Molina (coast) and in the Rayancancha town center (mountain) located in the department of Huánuco between the months of November (2018) and March (2019). During the growth and development of the crop, plant height and leaf coverage were evaluated at different stages; At maximum growth, the length of internodes, stem thickness, flowering intensity, corolla diameter, number of main and secondary stems, and leaf and terminal leaflet indices were evaluated. At maturity, the total weight and number of tubers per plant were evaluated. plant. In addition, the incidence and severity of important pests in the crop were evaluated. Under these conditions in La Molina (coast), in the summer, the morphotypes of native potatoes presented greater plant height, leaf cover, internode length, main stem diameter, number of main stems, leaf index and terminal leaflet. Likewise, I present a lower flowering intensity, number of secondary stems, total weight of tubers, number of tubers. Most of the evaluations carried out showed significant differences in the Student T test, except in the evaluation of the diameter of the corolla. Ten morphotypes that produced tubers under conditions of La Molina (coast) and the morphotypes most tolerant to pests and diseases were identified.
