2NDINTERNATIONAL WHEAT STRIPE RUST SYMPOSIUM

IZMIR, TURKEY

APRIL 28-MAY 01, 2014

PRIORITIES OF THE WHEAT BREEDING IMPROVEMENT

• Productivity • Resistance to disease:• Yellow rust• Leaf rust

• Drought and heat tolerance • Grain quality• Salt tolerance• Resistance to pests• Winter and cold tolerance

MAIN WHEAT DISEASES

Yellow rust - Puccinia striiformis f.sp. tritici

Leaf rust - Puccinia triticinia

YELLOW RUST EPIDEMIC IN UZBEKISTAN

• 1999: Yellow rust + Leaf rust• 2001: Yellow rust • 2005: Yellow rust + Leaf rust• 2009: Yellow rust • 2010: Yellow rust • 2013 : Yellow rust + Leaf rust• 2014: Yellow rust

RESISTANCE TO YELLOW RUST OF THE NEW PERSPECTIVE WHEAT VARIETIES (UZSRIPI - 2013)

NURSEREY TRAILS (2014 year)

• 17 IWWYT-IR 24• 16 IWWYT-SA 36• 21 FAWWON-IR 170• 20 FAWWON-SA 108• 13 YT-CAC-IR 36

Nursery name Number of samples

STRATEGY OF SELECTION FOR RESISTANCE TO YELLOW RUST

• Monitoring the spread of yellow rust in different regions of Republic

• Collection, multiplication and storing the yellow rust spores.

• Determination of the effective resistant genes• Determination of the intermediate host of

yellow rust pathogen • Determination of resistance to yellow rust in the

germination phase

• Determination of resistance to yellow rust in the flag leaf stage

• Determination of resistance to yellow rust of genetic resources, the hybrid material (F2-F6), lines and new varieties

• Ecological testing of varieties and lines on productivity, drought, heat and winter tolerance

• Testing of new varieties in the State Commission of Uzbekistan for Variety Testing

• Primary the varieties and lines seed production after the test in the first year of the State Commission

Primary seed production of the new wheat varieties created together with Turkey-CIMMYT-ICARDA:Dustlik,Yaksart, Jayhun, Turkistan, Hazrat Bashir Gozgon and Elomon.

The area under these varieties is 129 000 ha., 2014

From this area there are 55 000 ha. super elite and elite.
