Iowa Russet is a russeted apple linked to Prof. J. L. Budd of Iowa. The fruit is medium sized, oblate to roundish oblate, and sometimes slightly oblique. It has deep yellow skin, a pale red blush on the sunny side, and patches and netlike veinings of russet. [S1]
The cultivar originated on Budd's farm in Iowa. The clearest extracted reading gives Shellsburg, Iowa. Another OCR-supported block gives Spellsburg. [S1]
The flesh is yellow with light yellow veinings. It is moderately juicy, mildly subacid, rich, and rated very good. The entry also describes a large, deep, obtuse cavity; a regular, quite deep, slightly plaited basin; a closed calyx; a small core; and large seeds. [S1]
Iowa Russet is described as a winter apple. The main description says it keeps “all winter.” The artificial key places it in the late winter russeted group and identifies its basin as smooth and deep. [S1]
The available packet does not give tree habit, productivity, disease behavior, parentage, release date, or direct cold hardiness language. Its inclusion in a South Dakota Agricultural Experiment Station bulletin on northwestern apples gives it regional historical context, but no zone claim should be inferred from that alone. [S1]
