2ND
INTERNATIONAL WHEAT STRIPE RUST SYMPOSIUM
IZMIR, TURKEY
APRIL 28-MAY 01, 2014

2. 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

3. MAIN WHEAT DISEASES
Yellow rust -
Puccinia striiformis f.sp. tritici
Leaf rust - Puccinia triticinia

4. 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

5. I. Uzbek Scientific Research Institute of
Plant Industry
 All work carried out on artificially
infected background
 Selection of parental forms by
resistance to yellow rust
 Hybridization
 Evaluation of collection samples,
hybrid material (F2-F6), lines and
varieties for resistance to yellow rust.
 Primary seed production of the new
varieties
BREEDING WORK ON THE CREATION OF THE YELLOW RUST RESISTANT WHEAT
VARIETIES CONDUCTED AS FOLLOWS:
II. Kashkadarya Scientific Research
Institute of Breeding and Seed
Production of Cereal Crops
 Selection of the parent forms and
hybridization for creation rust
resistant, drought, heat and low
temperature tolerant varieties
 Evaluation of hybrid material (F2-
F6),
 Control and competitive variety
testing
 Primary seed production of the new
varieties
III. Scientific Research Institute in Galla-aral, Karakalpakstan Institute of Agriculture,
Khorezm, Surhandarya and Fergana branches of Grain Institute.
 Ecological test of the new varieties in different regions of Republic

• 16 IWWYT-SA 36
• 21 FAWWON-IR 170
• 20 FAWWON-SA 108
• 13 YT-CAC-IR 36
Nursery name Number of samples

11. 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

12. • 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

13. 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.
