Research Project: HOST RESISTANCE AND POPULATION GENETICS OF RUST AND FUSARIUM HEAD BLIGHT (FHB) DISEASES OF SMALL GRAIN CEREALS

Location: Cereal Disease Laboratory

Project Number: 3640-21220-021-03
Project Type: Specific Cooperative Agreement

Start Date: Sep 03, 2009
End Date: Jul 31, 2014

Objective:
Identify sources of seedling and adult plant resistance to wheat stem and leaf rust, and oat crown rust; Map resistance genes and QTLs for resistance to cereal rusts; and Use molecular and virulence markers to determine pathogen population structure and migration patterns.

Approach:
Screen oat and wheat seedlings for rust resistance in the greenhouse; Screen oat and wheat adult plants for resistance in the field to rusts and FHB; Screen recombinant inbred (RI) populations for rust resistance in the greenhouse and field; and Use DArT and SSR markers to genotype RI populations; Determine virulence phenotype and molecular (SSR) genotype of rust and FHB pathogen isolates from the U.S.
