Dataset for: Open field assessment for late blight evaluation in HERLB population (First trial_Ecuador)

29 families potato were exposed to late blight under natural infection in Quito, Eucador (3050 masl Quito-Ecuador) during the rainy season in 2023. 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).
