Wiki Draft

Irkutsk is a baccata seedling apple or crabapple selection associated with Hansen in 1910. [S1] It was raised from seed collected from wild plants near Irkutsk in the Lake Baikal region of eastern Siberia. This gives it a clear Siberian origin and helps explain why it appears in prairie apple literature. [S1]

The surviving description is brief but clear. The fruit was judged "too small for profit," so Irkutsk was not remembered as a commercial dessert or market apple. [S1] Instead, it was valued for use as a rootstock and for its ornamental qualities. [S1]

The cited entry gives no fuller description of the fruit, season, storage, or tree habit. [S1] The source also does not state a hardiness zone directly, though its origin from wild Siberian seed and its inclusion in Prairie Canada references place it in a cold climate context. [S1]

Irkutsk is best understood as part of the Siberian Malus baccata line used in northern breeding and rootstock work, rather than as a notable fruit cultivar in its own right. [S1] A separate low confidence lineage note links it as a parent in Jonathan apple x Irkutsk, but that refers to later breeding use, not Irkutsk's own parentage. [S1]
