Identification of Elite Potato Clones with Resistance to Late Blight Through Participatory Varietal Selection in Peru

Abstract Potato is the most important crop in Peru and late blight main disease affecting crop. However, new varieties that are resistant to often lack other traits farmers consumers prefer. Using participatory varietal selection, this study seeks identify clones with high potential become resistance but also feature a marketable tuber yield preferred agronomic traits. During 2016–2017, 36 previously selected for levels of from population B developed by International Center, three used as controls (INIA 302 Amarilis moderately resistant, INIA303 Canchan Yungay susceptible blight), were evaluated five Peruvian locations. At harvest, based on (i) evaluations made through Participatory Varietal Selection, (ii) analysis mixed models Best Linear Unbiased Predictors yield, (iii) low glycoalkaloid content tubers, (iv) good organoleptic quality. These again during 2017–2018 four Resistance yields identified criteria selection potato variety. The CIP308488.92, CIP308495.227 CIP308478.59 promising having superior local varieties, INIA-303 Canchan, Yungay, well quality content. can be suggested variety release similar agroecological environments.
