Selected as the best seedling from several one year old Siberian Crab seedlings collected by Niels E. Hansen on a trip to Russian in 1897.  Released in 1917, the Dolgo was prized as a rootstock for its cold hardiness and often planted as a shelterbelt tree in the Great Plains.  Prized for its bright red fruit and ability to "jelly" easily and produce tasty pink cider it was also popular for kitchen use.
