Pear breeding in Korea was started in the late 1920s and full-scale conventional breeding program has been carried out at the National Horticultural Research Institute (NHRI) since 1967. Good results have been obtained in a short period. High quality cultivars such as Whangkeumbae, Whasan, and Wonwhang have been released to private orchards and local performance testing for several promising selections are underway at different sites to select superior cultivars suitable to the Korean climate and soil conditions. The main breeding objectives include (1) very early cultivars with large fruit ripening in July; (2) disease and pest resistance, mainly black spot caused by Alternaria kikuchiana, scab by Venturia nashicol, and mite; (3) development of labor-saving varieties using self-compatibility, spur or dwarf types; and (4) development of new breeding technique using biotechnology such as gene transformation and DNA selection marker.
