Achieving improved genetic gain for yield in chickpea, faba bean and lentil using genetic diversity

In Australia, grower profitability of chickpea, faba bean, and lentil production faces challenges due to a limited genetic diversity among existing crops, resulting in minimal yield improvements of less than 0.5%. This issue stems from the use of a narrow range of genetic material in breeding programs, rendering these crops vulnerable to environmental stresses, the impact of climate change, and impeding the development of higher-yield varieties. However, recognising the vital role of genetic diversity in crop enhancement, recent advancements in biotechnology and breeding methods offer promising opportunities. By incorporating genetic diversity from wild relatives and employing cutting-edge technologies like speed breeding, genomic selection, and AI-guided breeding, there is potential to achieve an unprecedented 1.5% increase in yield genetic gain for these pulse crops. This investment aims to harness a rich pool of genetic resources, both locally and globally, to create robust, high-yielding pulse varieties adapted to diverse environmental conditions, benefiting Australian pulse growers and breeding programs.
