2006 Annual Report 4d.Progress report. This report serves to document research conducted under a specific cooperative agreement between ARS and Texas A&M University. Additional details of research can be found in the report for the parent project 5440-21000-025-00D. 80-100 entries from the USDA-ARS-coordinated Southern and Northern Regional Performance Nurseries, and 250-350 entries from the Regional Germplasm Observation Nursery were planted at Castroville and McGregor, TX for evaluation of stripe rust resistance. Environmental conditions during the 2006 growing season were characterized by severe drought, and stripe rust did not develop. Entries from the 2006-2007 Southern and Northern Regional Performance Nurseries, and the Regional Germplasm Observation Nursery, will be seeded in the fall of 2006 for evaluation during the 2007 season. Two-hundred and sixty stripe rust resistant lines were identified under a natural epidemic at Mead, NE in 2005. These materials will be reseeded in the fall of 2006 and lines with promising agronomic performance will be tested in south Texas nurseries in subsequent years.
