Wiki Draft

Mendel is a pear cultivar described as a seedling selected by William Pfander Jr. of New Ulm, Minnesota, in 1920. [S3] Prairie sources place it in the northern fruit growing orbit of Minnesota and Manitoba, and a South Dakota extension table later listed Mendel among pears recommended for trial in Zones I and II. [S2] The name also appears in prairie apple references for a different cultivar, so the pear and apple records should not be merged. [S1] [S3]

Sources describe the fruit as large to medium, pyriform, and yellow, with firm, juicy, moderately tender flesh and good quality. [S3] Its season is early September. [S3]

The tree is described as upright, vigorous, and only moderately hardy, not fully ironclad. [S3] A key prairie note says it fruited near Miami, Manitoba, which is direct evidence that it could bear in a cold prairie setting. [S3] The South Dakota trial listing supports that broader northern Plains context, but it is only a recommendation table and does not replace direct hardiness language. [S2]

Mendel fits into the prairie pear story as a northern seedling with documented bearing in Manitoba and enough promise to be circulated for trial farther south on the Plains. [S2] [S3] The surviving evidence is brief, but it preserves the essentials: a Minnesota origin, an early September yellow pear of good quality, and a tree with useful prairie adaptation but only moderate hardiness. [S3]
