2007 Annual Report 1a.Objectives (from AD-416) The objective of this cooperative research project is to screen the core collections of Lycopersicon wild species and four related Solanum spp. maintained in the National Plant Germplasm System for resistance to bacterial speck race 1. 1b.Approach (from AD-416) The core collections for wild species of Lycopersicon (212 accessions) and four related Solanum spp (20 accessions) will be screened for bacterial speck race 1 resistance. These will be grown in 12 replicates with 3 plants per replicate in the greenhouse and will be inoculated with bacterial speck race 1 and then maintained at 100% humidity in the greenhouse at 250C for one week. The plants then will be maintained in a greenhouse for 2 weeks when they will then be scored for lesion development on a reaction scale. Experiments will always include uninoculated controls. All experiments will be repeated at least once and if resistance is suspected, there will be more repeats. 3.Progress Report This report serves to document research conducted under a specific cooperative agreement between ARS and the University of California. Additional details of this research can be found in the report for 1907-21000-016-00D entitled "Conservation and Utilization of Germplasm of Selected Vegetable Crops." Two hundred seventy four (274) accessions from the C. M. Rick Tomato Genetics Resource Center have been evaluated to date. None of the accessions appeared resistant in our greenhouse screening. We will complete the re-evaluation of select accessions this fall. Monitoring activities for this project include annual reports and meetings of the Crop Germplasm Committee for tomato at the Tomato Breeder’s Roundtable Meeting.
