Krantz combines yield and specific gravity equal or exceeding that of Norgold Russet with exceptional boiling and baking qualities. Krantz processes well for fresh or frozen french fries. Plants are medium-late maturity, tall, vigorous and upright. Stems are medium thick with a reddish tinge at the nodes. Wings are straight, single, but not prominent.
Secondary leaflets are small, between primary leaflets.
The inflorescence is on a long peduncle, with reddish buds, large white corollas and green anthers. Tubers are oblong to slightly blocky, russet-skinned, with shallow eyes, white flesh and short dormancy. Tuber bulking occurs early. Tuber netting is very light in some soils or under certain growing conditions. Krantz has high resistance to common scab and hollow heart, with very high field resistance to late blight, and moderate resistance to Verticillium.
