Mercer Crab is known here mainly as a parent and reference cultivar in early northern breeding work. The bulletin names it as the wild crab parent in the cross Alexander apple x Mercer wild crab that produced Nebo. It also recommends keeping Forest King "in the collection along with Mercer and Missouri Giant," which suggests Mercer Crab was used as a comparison fruit in the hardy crabapple group under evaluation. [S1]
This source does not give Mercer Crab a full profile. The cited page gives no direct fruit description, ripening season, storage note, tree habit, or disease account for Mercer itself. Instead, Mercer appears in the breeding record and collection context of the South Dakota hardy fruit program, where parentage, keeping quality, and usefulness in northern conditions were central concerns. [S1]
The surrounding discussion places these entries among large fruited American wild crab and apple crab hybrids used for northern breeding. It notes that such material was often treated botanically as Pyrus Soulardii, a natural hybrid group involving Pyrus ioensis and Pyrus malus. The page does not explicitly assign Mercer Crab to that classification, so its exact botanical placement should remain open here. [S1]
Mercer Crab also matters beyond Nebo. Pomologica lineage links connect it with other crabapple breeding relationships, including Sweet Russet Crab, Progress Crab, and Toriy Crab. This shows it was part of a broader web of hardy crab material, not an isolated name. [S1]
