A potato clone with frost resistant foliage designated Alaska Frostless has been selected from the progeny of crosses involving Solanum acaule and commercial varieties. Its chromosome number is (2N=5X=60). Nearly mature vines have withstood field frosting at-3 C for 2 hours and have recovered from several frosts of-2 C. Yields in cwt per acre of tubers 2-3.5 inch in diameter have equaled those of Alaska's standard varieties. Dry matter of 21.7% is equivalent to that of the Green Mountain variety. Tubers are flattened, round, smooth and white with a nonuniform faintly purple blush after exposure to light. Culinary quality, flavor, and texture are very good. © 1969 Springer.
