Race analysis undertaken by EIAR, Ambo, GRRC, Denmark and USDA-ARS CDL on samples collected in 2015 from Ethiopia and Kenya indicates that stem rust populations in East Africa are changing. The detection of race TKTTF (“Digalu” race) in Ethiopia in … Continue reading
Following the recent release of the 2013 stripe rust report, the Global Rust Reference Center in Denmark has now just published the latest report detailing the results of race analysis for Puccinia striifromis samples submitted during the period January – … Continue reading
Analysis undertaken by the Small Grains Institute, Agricultural Research Council (ARC), South Africa indicated the continued predominance of stem rust race TTKSF in South Africa. Race TTKSF is one of the Ug99 lineage races, although it is avirulent on Sr31. … Continue reading
Analysis undertaken by AAFC, Canada on stem rust samples collected by NARI, Eritrea in Oct. 2011 has confirmed the continued presence of Ug99 lineage race PTKST in Eritrea, but only 1 sample out 15 was typed to this race. All … Continue reading
Knowledge relating to where stem rust is occurring is important, but information on which pathotypes (races) are present and at what frequency is vital for breeding and cultivar recommendation. The only way to determine virulence combinations and which specific pathotype … Continue reading
Confirmed results from race analysis completed in the 2009/10 season are now available. The confirmed spread of Ug99 variants carrying combined Sr31 + Sr24 virulence in Africa continues, along with the continued predominance of these variants in Kenya. The absence … Continue reading
Analysis of dead, single pustule stem rust pathogen samples (D-samples) using molecular diagnostic SNP assay at the USDA-ARS Cereals Disease Lab, Minnesota has detected a race TKTTF (“Digalu” race) genotype in Kenya for the first time. Five samples from 2014 … Continue reading
Mehran Patpour (Global Rust Reference Center in Denmark) and co-authors have just published details of the emergence and spread of virulence to SrTmp in the Ug99 race group in Africa. The note is now available as a First Look in … Continue reading
Following the confirmed detection of Ug99 (race TTKSK) in Egypt in 2014 (BGRI special newsletter report April 2015) increased vigilance is needed for stem rust in the eastern Mediterranean. Although no confirmed reports of race TTKSK have been obtained from … Continue reading
