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
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

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.
