Pf 51 is recorded as a standard apple entry noted as Pf 51 with parentage Haralson x Rescue, associated with Edmonton and cited with 1974 [S1]. The entry is marked “ST,” meaning a standard-sized tree type with fruit diameter 5 cm or more [S1].
Fruit is described as 6–7 cm, light green with red streaking on exposed surfaces [S1]. It is round, with a very small shallow lipped and russeted cavity, a small shallow blush, greenish flesh, small but prominent basin lenticels, and sometimes entire-fruit russeting [S1].
Flavor is crisp with slightly tough skin; the flesh is juicy, sweet, and aromatic. It is rated as good for cooking and excellent for dessert use [S1]. It matures early to mid-September, should be picked when fully ripe, and stores for about three months, with firmness retained longer than color and flavor [S1]. The tree is described as strong framed and exceptionally vigorous [S1]. The source also notes “FB2,” interpreted as moderate susceptibility to fireblight injury [S1].
