Narrative

Oregon’s Home Orchard Society (HOS) voted at their November 2018 annual meeting to name a favorite pear selection in memory of long-time member Jerald (Jerry) Shroyer who was born on November 24, 1932 and died on November 9, 2017. Shroyer’s Sunset (PI 541201) is a delicious little pear that was among hundreds of varieties transferred to the USDA National Clonal Germplasm Repository when it opened in 1981 from Oregon State University’s Experiment Station near Medford. Little is known about this un-named selection from Canada, other than it was from a cross made in 1925 by O.A. Bradt in Ontario. The catalog at the Southern Oregon Experiment Station listed this pear as HES 25021, the letters presumably an acronym for ‘Harrow Experiment Station’. There are no records to link this selection to a particular pedigree, however the fruit resembles the cultivar Seckel in size, shape and coloration, although it tends to be slightly larger than ‘Seckel’. The fruit ripens in mid-September, and like ‘Seckel’ has superb texture and flavor. HES 25051, now Shroyer’s Sunset, has been a favorite of HOS members during their annual visits to the USDA Pear Repository in Corvallis.
