What is being done to address constraints?
• Climate resilient crop germplasm
• Climate resilient crop management practices
• Partnership for efficient delivery
• Climate resilient policy (needed)

New Initiatives on crop improvement
• CGIAR Research Programs (CRPs)• Dryland Systems• WHEAT• Dryland Cereals• Grain Legumes
•
![Page 33: Role of international collaboration towards improving crop productivity in the context of climate change and food security in Central Asia – an overview](https://reader035.vdocuments.site/reader035/viewer/2022062513/55502cf0b4c9059f318b4ba5/html5/thumbnails/33.jpg)
CRP WHEAT – outputs relevant to the Central Asia region• More productive wheat varieties with package of traits:
• High yield• Improved quality (end-use, market)• Improved input-use efficiency • Stress tolerance
• Abiotic – drought, heat, salinity, frost, cold• Biotic – yellow rust, leaf rust, Septoria, tan spot, Fusarium, Sunn Pest,
Russian Wheat Aphid, Hessian fly
• Seed sector improvement • Conservation agriculture and other resource conserving
technologies• Capacity development
![Page 34: Role of international collaboration towards improving crop productivity in the context of climate change and food security in Central Asia – an overview](https://reader035.vdocuments.site/reader035/viewer/2022062513/55502cf0b4c9059f318b4ba5/html5/thumbnails/34.jpg)
Policy reforms needed
• Free movement of crop germplasm in the region
• Reduce the number of years from introduction to release of variety to the farmers : (reduce from 9 to 5 years)
• Farmers’ participation in selection of new varieties
• Harmonize varietal release and seed policy for the region
• Promote replacement of low yielding, disease susceptible varieties with high yielding, disease resistant varieties
• Diversify and intensification of cropping system
• Technologically, each country in Central Asia could produce enough wheat for home consumption, but with right policy

Central Asia highlighted in WHEAT CRP Report 2013: outcome and impact
• Zero-till scale-out and -up in Kazakhstan
• WHEAT competitive partner grant for Uzbekistan and Tajikistan (where wheat crops have suffered three major yellow rust outbreaks in the last five years), multiplied seed of resistant varieties on state farms and farmers’ fields, and in 2014/15 more than 20,000 ha of winter wheat will be planted to prevent future damage from yellow rust

Summary
• International collaboration in Central Asia • Climate resilient, stress tolerant crop varieties ready for
deployment• Opportunities in CRP WHEAT for Central Asia• Policy reforms need
