Tetofsky is a Russian selection imported by the Massachusetts Horticultural Society in 1835, and prairie apple records note it was being grown and exhibited in Manitoba about 40 years later [S1].
It is listed as a CR type (crabapple/applecrab, fruit under 5 cm), with greenish yellow fruit, and also appears under the spelling Tetrofsky [S1].
Performance notes are mixed: a 1991 comment calls it "too tender" and "a good breeder," while a 1950 catalog says it is a quick bearer of red apples; it is also said not to be as good as Yellow Transparent. The source includes an H2-3 hardiness marker, which it describes as moderately to borderline hardy [S1].
