Wiki Draft

Red Duchess is an apple cultivar recorded as a sport of Duchess and listed from Stockport, New York, in 1943. [S1] The surviving description is brief but clear. It is a medium apple, almost solid red in color, and classed as a dessert fruit. [S1]

South Dakota extension material also lists Red Duchess among summer apples recommended for both cooking and eating. It was listed for all three South Dakota fruit growing zones, including the northern two thirds of the state. This suggests broad regional usefulness under Upper Plains conditions, though no formal hardiness zone number is given. [S2]

Later South Dakota nursery listings show Red Duchess still in commerce through at least two nurseries. This indicates it was not only described in reference works but also offered to growers in the region. [S3] The available sources add little on tree habit, disease, storage, or parentage beyond its identity as a red sport of Duchess. Its main historical interest here is as a colored Duchess mutation considered useful enough for prairie recommendation and nursery sale. [S1] [S2] [S3]
