  • 1. New sources of stripe rust resistance in international winter wheat nurseries evaluated in Uzbekistan in 2013 O. Amonov, Z. Ziyaev, D. Musurmonov, S. Alikuov, A. Amanov, R. C. Sharma 2ND INTERNATIONAL WHEAT STRIPE RUST SYMPOSIUM IZMIR, TURKEY APRIL 28-MAY 01, 2014
  • 2. Wheat in Uzbekistan (2012) • Area: 1.4 million ha • Production: 6.5 million t • Productivity: 4.7 t/ha Source: FAO, 2013
  • 3. CONSTRAINTS OF WHEAT PRODUCTION IN UZBEKISTAN • Yellow Rust • Leaf rust • Terminal heat stress • Salinity • Low soil organic matter content • Weed problem (costs causing less use of herbicides) • Sun pest
  • 4. WHEAT BREEDING OBJECTIVES • High and stable grain yield • Good bread-making quality • Earliness • Plant height (90-100 cm) • Resistance to diseases • Winter hardiness • Drought resistance • Heat tolerance • Salt tolerance • Resistance to lodging

  • 14. New Variety identified in 2013 to be submitted in 2014 Shark-1/3/Agri/Bjy//Vee/4/Shark/F4105W2.1 YR =0 GY =8.4 t/ha
  • 15. Uzbekistan hosted International Winter Wheat Travelling seminar (20 – 25 May 2013) Around 50 scientists from 11 countries participated
  • 16. Summary • More than 100 new lines resistant to stripe rust were identified in international nurseries evaluated under severe epidemics (inoculated and natural) in Uzbekistan in 2013 • Ten stripe rust resistant lines, superior for grain yield, and with acceptable quality and agronomic traits are being evaluated in 2014 • One candidate cultivar was identified for submission to State Variety Test Commission in 2014 I would like to summarize my presentation here
  • 17. Thank you for attention
