Tubers have excellent resistance to splitting and some resistance to bruising. Trials have found good resistance to potato virus Yo, dry rot (Fusarium coeruleum) and skin spot. This variety has low resistance to potato leafroll virus and late blight on tubers. Tests for resistance to potato cyst eelworm demonstrated resistance to Globodera rostochiensis Ro1 and susceptibility to Globodera pallida Pa 2/3, 1.
