Fifty Years of Pear Breeding: An Overview of the Harrow (Ontario, Canada) Pear Breeding Program
The ‘Harrow’ (Ontario, Canada) pear breeding program was initiated in 1962 to develop fire blight resistant pear selections for the fresh and processing markets. Six cultivars have been introduced for commercial production in Canada, some of which have been protected and introduced in Europe. Several additional selections have been protected in Canada and will be introduced in the near future. Two cultivars have been protected, named and introduced to the European market. All selections and introductions have good to excellent resistance (but not immunity) to natural fire blight infections.
