Tanya is a pear from N. E. Hansen's hardy fruit work. A 1939 source lists it as a cross of Ideal x East Siberian pear and identifies it as Pyrus ussuriensis.[S1] The entry places it among pears described as resistant or immune to fire blight, which is its main historical context in the bulletin.[S1]
Sources describe Tanya as a red, medium sized, late keeping pear of good quality.[S1] The surviving description is brief, but it clearly presents Tanya as a storage pear rather than an early use fruit.[S1]
The tree is described as hardy and blight resistant.[S1] The bulletin does not give a formal hardiness zone, but its inclusion in a work on new hardy fruits for the Northwest and northern Great Plains places Tanya in a cold climate breeding context.[S1]
Its recorded parentage matters because it links the named pear Ideal with East Siberian pear genetics and shows the period effort to combine fruit quality with northern hardiness and disease resistance.[S1] No fuller account of its later dissemination, commercial uptake, or descendant use appears in the cited material.[S1]
