Joshua is a late maincrop variety. This variety is particularily suitable for crisping. Tubers have some resistance to bruising and splitting. Trials have found good resistance to dry rot (F. coeruleum and F. sulphureum). This variety has low resistance to late blight on tubers, powdery scab and potato leafroll virus. Tests for resistance to potato cyst nematode demonstrated susceptibility to both Globodera rostochiensis Ro1 and Globodera pallida Pa 2/3, 1.
