Delus: a new variety of potato, immune from the common races of the late blight fungus, high in percentage total solids, and adapted to growing conditions in delaware

Abstract

Delus (B 73–18) is resistant to late blight. It is less susceptible to scab than Katahdin and Irish Cobbler. In comparative trials in Delaware it yields as well as if not somewhat higher on the average than the two standard varieties Katahdin and Irish Cobbler. It ranks high in market and cooking qualities. In Maine it compares favorably in yield with Katahdin and Irish Cobbler and is usually higher in dry-matter content. In Delaware it developed internal mahogany browning after 6 months of storage at temperatures ranging from 34° to 38°F. It kept well in storage at Beltsville, Maryland, where the storage temperature averaged 40° during the winter months.
