Attention California pear growers: A new pear cultivar called Gem has been released by the U.S. Department of Agriculture (USDA), Oregon State University, Michigan State University, and Clemson University.

Gem is ideal for the fresh market. It combines high yields with excellent appearance, fruit quality, and long storage potential.

The new cultivar is resistant to fire blight and is not prone to brown discoloration, called ‘superficial scald’ which affects some pear varieties.

Agricultural Research Service Horticulturist Richard Bell at the Appalachian Fruit Research Station in Kearneysville, West Virginia, and his colleagues described Gem in the March 2014 issue of HortScience.

Gem requires at least three weeks of cold storage before normal fruit softening, but it will last for at least 28 weeks in cold storage without core breakdown or superficial scald.

The fruit can also be eaten immediately after harvest without softening, as it has a crisp, juicy texture. Its flavor is sweet and mildly aromatic.

When compared to Bartlett, a popular pear variety, sensory panelists rated Gem similar in appearance, flavor, and purchase intent.

The original seedling tree of Gem was from a cross of ‘Sheldon’' and US62563-004 made in 1970. Bell selected Gem in 1981 from the seedling orchard at ARS’ Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, Md.

The source of Gem's fire blight resistance comes from the cultivar ‘Barseck.’

Subsequently, Gem was evaluated for fruit quality, fire blight resistance, and productivity in replicated trials at the Kearneysville location and at research centers at Washington State University, Oregon State University, Michigan State University, Cornell University, and Clemson University.

Gem is recommended as a fresh-market pear for commercial and residential orchards. While budwood of Gem is limited, genetic material of this release will be deposited in the National Plant Germplasm System, where it will be available for research purposes, including development and commercialization of the new cultivar.

ARS is the USDA’s chief intramural scientific research agency, and this research supports the USDA priority of promoting international food security.
