Proceeding of International Conference on Wheat Stem Rust Ug99- A Threat to Food Security p. 28-34Summary: Race Ug99 of wheat stem rust pathogen Puccinia graminis is not just spreading beyond East Africa but also evolving to overcome additional race-specific resistance genes. Use of non race-specific, adult plant resistance (APR) conferred by multiple minor genes is therefore considered to be a better strategy to curb evolution. Screening of wheat materials in Kenya and Ethiopia from 22 countries and International Centers has identified low frequency of lines that have high to adequate levels of APR and can be deployed as varieties. Shuttle breeding schemes with Kenya or Ethiopia are currently being used by CIMMYT and ICARDA to enhance the selection of new high-yielding wheat lines with high level of APR.
