Meeting the Challenge of Yellow Rust in Cereal Crops - ICARDA

188
Conclusion
Relatively old bread wheat cultivars of Ethiopia originating from Kenya,
Kenyan cultivars and CIMMYT advanced lined used as supplemental yellow
rust differentials demonstrated durable resistance in Ethiopia. However, it can
be concluded that most of the commercial cultivars released during 1997
became susceptible to yellow rust shortly after release. The recurrent outbreaks
of yellow rust disease could be due to a combination of lack of information
about recent developments of the pathogen races in the region and the
continuous release of cultivars with similar parentage. Future breeding
programmes should involve the exploitation of genes present in the cultivars
that have proven to have a quantitative type of resistance. To sustain wheat
production in the region in general, and particularly in Ethiopia, monitoring of
races and inventorying of resistance genes are of prime importance.
