Tetofski, also written Tetofsky, is a Russian apple described for northwestern growing conditions in A Study of Northwestern Apples [S1]. The tree is hardy, very upright, and bears early and annually [S1].
The fruit is medium or smaller, oblate to roundish oblate, somewhat conical, and angular [S1]. The skin is smooth yellow, striped and splashed with bright crimson, marbled on the sunny side, and covered with a heavy whitish bloom [S1]. The source calls it handsome [S1].
The flesh is white, juicy, sprightly acid, and good [S1]. The season is August [S1]. The available source gives no storage duration or culinary use beyond the flavor description.
The tree description is brief: Tetofski is hardy, strongly upright, and bears early and annually [S1]. The entry gives no disease observations, rootstock notes, or pruning guidance.
Hardiness is supported by the direct statement that the tree is hardy, in a bulletin about apples for northwestern and northern prairie conditions [S1]. No USDA or Canadian zone rating is stated.
The source places Tetofski among cultivated apples, but gives no direct parentage, breeder, release date, or institutional origin beyond Russia [S1]. A later note explains the spelling: Downing used Tetofsky, Warder used Tetofski, and the bulletin uses the final “i” spelling [S1].
