Research on host resistance to apple pests at the USDA Plant Genetics Resources Unit, Geneva, NY

Clayton Myers, cmyers@afrs.ars.usda.gov, USDA-ARS, Appalachian Fruit Research Station, 2217 Wiltshire Road, Kearneysville, WV and Philip L. Forsline, PLF1@cornell.edu, USDA-ARS, Plant Genetics Resource Unit, Cornell University, 630 W. North Street, Geneva, NY.

The Plant Genetics Resources Unit (PGRU) in Geneva, NY houses over 4,000 apple accessions that represent over 90% of the known genetic diversity of Malus spp. worldwide. Included in a core collection of about 195 accessions are numerous cultivars of the domestic apple, M. x domestica, as well as it's parent species Malus sieversii. Selected accessions from this core collection, as well as numerous accessions of Malus sieversii recently collected from Kazakhstan, are being screened and tested for potential resistance to major apple pests, including plum curculio, codling moth, oriental fruit moth, and apple maggot.
