This project aims to identify mechanisms contributing to stress tolerance in chickpea and the information on tolerance mechanisms can then be used in breeding programs in the development of stress tolerant cultivars for Australia and India. Thus, the project’s aims are to: (i) elucidate the processes in the reproductive phase of chickpea most susceptible to heat, drought and salinity stress; (ii) identify sources of tolerance across stresses and the physiological mechanisms involved; (iii) further our understanding of salinity tolerance of reproduction and validate salinity tolerance quantitative trait loci (QTL); and (iv) initiate breeding for multiple stress tolerance by developing multi-parental crosses involving stress-tolerant chickpea genotypes. The new knowledge will provide the basis of future breeding programs for improvement of stress tolerance in chickpea cultivars for Australia and India.
