Peter is a pear introduction from the University of Saskatchewan. In 1960 it was recorded as PR. No. 6 Peter. Its parentage is given as Pyrus ussuriensis × Aspa, and the 1960 introduction record describes it under non irrigated field conditions at Saskatoon.[S3] Later Saskatchewan notes describe Peter as a medium sized pear, about 2 1/4 inches long, with excellent quality when properly ripened.[S2]
In 1960, the fruit was described as about 2 1/8 by 2 inches, ripening in mid to late September, with moderately thin skin. That record rated its quality as very fair and said the fruit held up fairly well.[S3] A later Saskatchewan summary is more favorable. It calls Peter a medium sized pear with excellent quality when properly ripened.[S2] The same source says these pears should be picked before they are fully ripe and finished indoors, or they may brown at the core.[S2]
Its hardiness appears moderate, not extreme. Saskatchewan guidance says Peter appears hardy enough for home gardens in Zones 3B, 4, and 4A, but it has shown severe injury at some sites in Zone 5.[S2] The introduction and trial context at Saskatoon, together with its P. ussuriensis background, place it within the prairie breeding effort to produce usable pears for cold regions. The packet does not give more detail on its breeder, naming story, or later breeding use.[S3]
One source in the packet names a different fruit with the same name: an apple cultivar called Peter, a seedling of Wealthy raised by Peter M. Gideon in Excelsior, Minnesota.[S1] That apple does not match the Saskatchewan pear introduction and should be treated as a separate cultivar that shares the name.[S1]
