Heyer #20 is an apple cultivar listed with unknown parentage, associated with the name Heyer around 1936, described as a standard tree with fruit around 7 cm (yellow with a pink cheek) and a vigorous growth habit [S1]. It is described as slightly late but a better keeper than Heyer #12 [S1].
The entry notes mixed cold-climate performance signals: it has an H2-3 hardiness code, interpreted as moderately hardy to borderline hardy, and Manchester specifically said it had not proven as hardy as Jarvie [S1]. Erskine recommended it, while Coutts (1991) called it obsolete and called it a fair breeder [S1]. The cultivar page also records FB2 (a fireblight-related code in the legend) and cites BHB, expanded as Bart Hall-Beyer and Richard, Ecological Fruit Production in the North (1983) [S1].
