Interpretive Summary: ‘A93157-6LS’ is a high-yielding potato cultivar suitable for both fresh consumption and for processing into frozen potato products. It is notable for its ability to retain low levels of sugars in its tubers following long-term storage. Low levels of tuber sugars contribute to light-colored French fries and frozen potato products that are desired by consumers. A93157-6LS was released in 2006 by the USDA-Agricultural Research Service and the Agricultural Experiment Stations of Idaho, Oregon, and Washington.

Technical Abstract: ‘A93157-6LS’ is a russet-skinned, high yielding, potato cultivar suitable for processing or fresh-pack. The “LS” in its clonal designation is an abbreviation for “Low Sugar”, and is descriptive of this cultivar’s resistance to the accumulation of reducing sugars in its tubers. This characteristic allows tubers of A93157-6LS to be stored at temperatures as low as 5.6 C for 250 days without the need for reconditioning prior to processing. The colder, storage temperatures, associated with the low temperature sweetening resistance of A93157-6LS, contributes to prolonged tuber dormancy and quality, and to a reduction in the incidence and severity of storage diseases associated with the higher storage temperatures typically used for industry standard cultivars such as “Russet Burbank” and ‘Ranger Russet’. A93157-6LS was released in 2006 by the USDA-ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington, and is a product of the Northwest Potato Variety (Tri-State) Development Program. In full-season trials conducted over a three-year period in the states of Idaho, Oregon, Washington, Colorado, California, New Mexico, and Texas, A93157-6LS averaged 5% and 4% higher yields than Ranger Russet and Russet Burbank, respectively and had a higher percentage of U.S. No. 1 yield than either cultivar. Specific gravity of A93157-6LS is high, with values consistently greater than those of Ranger Russet or Russet Burbank. A93157-6LS is resistant to common and powdery scab, very resistant to the common strain of potato virus Y (PVYo), and also is moderately resistant to Verticillium wilt, early blight of the foliage and tuber, Pectobacterium soft rot, and to galling of roots by powdery scab. It is susceptible to all other potato diseases and pests. Blackspot bruise reaction for A93157-6LS is similar to that of Ranger Russet. The incidence of hollow heart in A93157-6LS is higher than that of Ranger Russet or Russet Burbank. Cultural recommendations to manage hollow heart in A93157-6LS are provided.
