Description 3148 genotypes from forty biparental populations from crosses of wild potato species S. megistacrolobum, S. microdontum, S. tarijense and self-compatible (SC) 2x hybrid derived from crossing 2x landraces with SC sources of S. chacoense were exposed to late blight under natural infection in Chontabamba, Oxapampa (1810 masl Pasco-Perú) during the rainy season in 2019. Statistical Augmented row-column design without replication of 3 hill plots was properly established, three varieties with known late blight response were included as controls. After 40 days after planting (DAP), the percentage of leaf area affected by late blight infection was recorded by plot throughout the season to subsequently compute the area under the disease progress curve (AUDPC).
