Abstract: El cambio climático está alterando los diferentes ecosistemas de diversos cultivos afectando su rendimiento y producción. Actualmente, la papa nativa es de gran importancia en el Perú, por el aporte nutricional, el valor cultural existente en las comunidades campesinas y la diversidad genética que posee. Pese a ello, existe escasa información con respecto al efecto que causa las condiciones climáticas de costa en verano en el crecimiento y el desempeño agronómico en la papa nativa. En el ensayo experimental se utilizaron cincuenta morfotipos de papas nativas, los cuales se sembraron en la Molina (costa) y en el Centro poblado Rayancancha (sierra) ubicado en el departamento de Huánuco entre los meses de noviembre (2018) y marzo (2019). Durante el crecimiento y desarrollo del cultivo se evaluó la altura de planta y cobertura foliar en diferentes etapas; en el máximo crecimiento se evaluó la longitud de entrenudos, grosor de tallo, intensidad de floración, diámetro de corola, número de tallos principales y secundarios e índices de hoja y foliolo terminal, a la madurez se evaluó el peso total y número de tubérculos por planta. Además, se evaluó la incidencia y severidad de las plagas importantes en el cultivo. Bajo estas condiciones en la Molina (costa) en el verano los morfotipos de papas nativas presentaron una mayor altura de plantas, cobertura foliar, longitud de entrenudos, diámetro de tallo principales, número de tallos principales, índice de hoja y foliolo terminal. Así mismo presento una menor intensidad de floración, número de tallos segundarios, peso total de tubérculos, número de tubérculos. La mayoría de las evaluaciones realizadas presentaron diferencias significativas en la prueba T Student, excepto en la evaluación del diámetro de la corola. Se identificó diez morfotipos que produjeron tubérculos en condiciones de la Molina (costa) y los morfotipos más tolerantes a plagas y enfermedades.
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.
