Nertchinsk is listed as a baccata crabapple, with fruit under 5 cm, and is described as coming from Nertchinsk in eastern Siberia. The entry associates it with Hansen and gives the year 1924. [S1]
It is noted mainly for tree structure rather than fruit detail: a dwarfing stem builder with a very strong framework and good unions. Trees are said to bear well, although the University of Saskatchewan reported eventual incompatibility. The source also marks it H1, meaning hardiest. [S1]
