  2. 2. Highly Diverse & Challenging Region Yellow Rust in CWANA in 2010-2011 “The situation and Measures Taken” CWANA Kumarse Nazari k.nazari@cgiar.orgINTERNATIONAL CENTER FOR AGRICULTURAL RESEARCH IN THE DRY AREAS (ICARDA), ALEPPO, SYRIA Population: >1 Billion people 2011 BGRI Technical Workshop, JUNE 13-16, 2011
  3. 3. More than 50 m ha of wheat production in CWANA25% of the total global wheat areas fall in CWANA
  4. 4. Epidemiological Factors Conducive environmental conditions Genetic similarity of Mega-cultivar (Yr9 and Yr27) and susceptibility of genotypes and susceptible varieties (Turkey=Gerek, Iran= Sardari, Morocco= Akhtar,..) Means of transportation factors ▪ west-east wind movement and human Overlapping/ continues cropping system Widespread of alternate host and wheat wild relatives
  5. 5. Wide spread of new Yr race: Yr27 virulence race in southern partCool and humid weather in warm areaYellow rust epidemic, Darab, Dezful and Ilam, Kurdistan,Kermanshah 2007-2010

  16. 16. International Wheat Yellow Rust Trap Nursery – International Yellow rust Trap Nursery – Yellow rust differential cultivars – Yellow rust Avocet Near Isogenic Lines (NILs) – Known cultivars for APR genes – Commercial cultivars in CWANA – 76 location in 28 countries – Virulence for Yr2, Yr6, Yr7, YrA and Yr31 is fixed in all locations. – Yr5 and Yr15 are effective in all locations – Virulence for Yr9 and Yr25 was very common – Virulence on Yr1, Yr8, Yr10. Yr17, Yr18, Yr24, and Yr27 was varied – Frequency and distribution of virulence forYr27 is increasing very rapidly
