Enhanced food and income security in Southwest and Central Asia (SWCA) through potato varieties with improved tolerance to abiotic stress
Project
Project code: JKI-RS-08-1102
Contract period: 01.01.2008
- 01.12.2010
Purpose of research: Applied research
The project aims at the increase of food and income security of resource-poor farmers in Southwest and Central Asia (SWCA) by reducing the vulnerability of crop production to abiotic stresses. Stress tolerant potato varieties will contribute to the reduction of yield losses due to abiotic stress, thereby enhancing food production and productivity in stress-prone agroecologies (SWCA). The project will provide national programs and participatory networks of evaluators with improved germplasm, capacity and tools to utilize genetic diversity held in genebanks and reduce the time required to develop and deliver robust, farmer-ready varieties for productive, reduced-input cropping systems. For SWCA the main aims are (i) the development and exchange of early-maturing potato varieties adapted to stress-prone cropping systems developed and exchanged, (ii) the improved access of smallholder farmers to new potato varieties adapted to stress-prone environments (iii) development of screening methods and marker systems for key traits of abiotic stress tolerance adapted and applied for stress tolerance breeding, (iv) development of dynamic maps and models depicting and characterizing stress-prone agro-ecologies at present and under future climate change scenarios in use by NARS, regional governments and extension services. In the frame of this project the Institute for Resistance Research and Stress Tolerance will carry out the validation of candidate traits in 50 Solanum tuberosum accessions with divergent levels of drought tolerance analysing physiological parameters and gene expression by Real Time PCR. Results will on the one hand facilitate effective breeding for drought tolerance in the SWCA (see iii) but will also be the basis for the development of drought tolerant genotypes in Germany. This may be important in the future due to global warming.
