This pear is bred for fireblight resistance. It also has great scab resistance, but it is susceptible to pear psylla and moderately susceptible to pseudomonas. Extremely cold hardy, Harrow Delight will do well as low as zone 4. The tree is consistently productive, and fruit will need to be thinned for optimal size. Harrow Delight has demonstrated pollen compatibility with Bosc, Bartlett, Anjou, and Harvest Queen.

Harvested about two weeks before Bartlett, this pear is greenish-yellow with a red blush. Fruit should be picked while still green, as it has a strong tendency to drop as it ripens. Shelf life is also greatly reduced if the fruit is allowed to mature on the tree. These pears have excellent flavor. From Daniel Koeneman in Texas: "The pears are small but with an intense, complex flavor and smooth texture."

Harrow Delight was developed by the disease-resistant breeding program that was begun by Dr. R.E.C. Layne in 1962 at the Agriculture and Agri-Food Canada Research Centre at Ontario Canada. This work was continued by Dr. H.A. Quamme, and then Dr. F. Kappel. Other cultivars produced by the program include AC™ Harrow Crisp, AC™ Harrow Gold, and Harvest Queen.
