Wiki Draft

Manitoba Seedlings is a plum entry in the nigra group. The name refers to seedlings raised from wild pits sent from Manitoba and grown at the South Dakota Experiment Station. The evidence here points to a group of prairie native seedlings under evaluation for adaptation and fruiting performance, not to a single named released cultivar. [S1]

The surviving description in this source is mainly about origin and testing context. It says the seedlings were grown by the writer at the South Dakota Experiment Station from wild Manitoba pits. This ties them to early prairie plum exploration and station trial work, not to a formal breeding cross or a named commercial introduction. [S1]

This source page does not preserve a full fruit or tree description for Manitoba Seedlings itself. It does not support details on fruit size, color, flavor, season, storage, productivity, or hardiness beyond its placement in the nigra plum context and its Manitoba seed origin. [S1]

Manitoba Seedlings remains historically interesting because it reflects a period when experiment stations were testing wild and semi wild northern plum material as a possible foundation for hardy prairie fruit culture. In that sense, the entry belongs to the broader story of selecting useful plums from native or locally adapted germplasm rather than importing only established eastern or European sorts. [S1]
