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
