Research Project:
PLANT HOST INTERACTIONS IN APPLE GERMPLASM
Location: Kearneysville, West Virginia
2006 Annual Report
4d.Progress report.
This report serves to document research conducted under a reimbursable agreement between ARS and Cornell University. Additional details of research can be found in the report for the parent 1931-21000-015-00D Integrated Orchard Management and Automation for Deciduous Tree Fruit Crops. In collaboration with Dr. Harvey Riesig, Cornell University, and Phil Forsline, USDA-ARS Plant Germplasm Repository in Geneva, NY, bioassays and field observations were conducted in the Malus germplasm repository collection. Results indicate that:. 1)several Malus accessions (including numerous crabapple species from around the world) are resistant, or at least partially resistant to attack by internally feeding lepidopteran larvae, plum curculio, and apple maggot and. 2)the pest resistance mechanisms are tentatively elucidated. An understanding of the resistance levels and mechanisms in Malus germplasm will contribute to development of pest resistant cultivars requiring less pesticide usage. This project supplements the parent CRIS by providing detailed information on Component 1 (Integrated Production Systems), problem statement 2 (Integrated Pest Management) in National Program 305.
