Research Project: California-Adapted Barleys for Resistance to Stem Rust (Ug99)

Location: Forage Seed and Cereal Research

Project Number: 5358-22000-038-03
Project Type: Specific Cooperative Agreement

Start Date: Sep 28, 2010
End Date: Sep 27, 2014

Objective:
Produce F3 populations of California-adapted barleys crossed with sources of genes for resistance to the Ug99 stem rust pathogen.

Approach:
Make crosses between Ug99-resistant barley lines and various market types of barley adapted to California production. The Ug99 resistant lines will be from ICARDA/CIMMYT material previously tested by Brian Steffensen at University of Minnesota, hulless lines from UC Davis and spring 2-row barleys from Washington State University. The locally-adapted lines will include hulled spring barleys for malting. Conduct field evaluations of F2 populations for agronomic traits including cold tolerance and resistance to local diseases, then advance to the F3 generation for further testing. The materials resulting from this SCA will be available for further development and testing to select materials that are locally adapted and have resistance to Ug99. This SCA supports research conducted under National Program (NP) Number303, Plant Diseases. The research is conducted as part of ARS research project 5358-22000-035-00D, augmented by the FY2010 Program Increase for Research to Strengthen Grain Disease Research to Reduce World Hunger.
