Wheat Leaf Rust (Puccinia triticina) Epidemics and Host Plant Response in South Tigray, Ethiopia

Teklay Abebe Teferi

Abstract:
Leaf (brown) rust has been an important wheat disease in Ethiopia. Periodic epidemics are ongoing with grain losses up to 75%. Surveys were conducted in the Tigray area from 2010-2013 to monitor the spatial and temporal dynamics of the leaf rust pathogen population and host response. It was based on inspection of wheat fields randomly selected at 5-10 km intervals along accessible routes. Total 66, 52, 61 and 70 fields were examined in 2010-2013 with prevalence level of 35, 12, 20 and 17%, respectively. The disease incidence and severity reached 100% on Raya-Azebo and Raya-Alamata districts at many locations. The overall mean incidences and severities from 2010-2013 were 24 and 18%, 5 and 20%, 7 and 15% and 13 and 27%, respectively. Fifteen leaf rust differential hosts were found effective to the pathogen populations and could be used as potential sources for the development of resistant varieties.
