Intra- and interspecific diversity for stability, efficient resource use and adaptation to climate change
Project
Project code: 2822OE218
Contract period: 01.07.2024
- 30.06.2029
Budget: 54,550 Euro
Purpose of research: Applied research
Keywords: crop production, agricultural biodiversity, pea, genetic resources, climate change adaptation, weed, wheat, other cereals, organic farming
In the future, high performance must be achieved in conjunction with responsiveness to highly variable conditions, such as water supply, temperature extremes and biotic stress, which can no longer be combined in a single genotype or often not even in a single species. Due to their intraspecific diversity, heterogeneous populations are particularly able to respond dynamically to environmental influences. In addition, especially under reduced N inputs, interspecific diversity may contribute, e.g. in baking cereals, to achieve the required protein and wet gluten contents, e.g. by admixing peas to ensure the nutrient supply at the right time, whereby intraspecific diversity stabilizes the behaviour of wheat in species mixtures. The central hypothesis of I2C5 is that the combination of intra- and interspecific diversity (I2) with appropriate genetic composition are efficient and forward-looking methods to achieve the traits that we call the '5 Cs': Complementation, Capacity, Compensation, Cooperation and Change (adaptation through change). The overall objective of I2C5 is (a) to evaluate the potential of heterogeneous populations and species mixtures in terms of their climate resilience and product quality and (b) to contribute to the development of breeding methodology in order to optimize intra- and interspecific diversity on the one hand, and to include existing populations in further breeding on the other. In addition to wheat, heterogeneous populations of spelt will be developed for the first time and breeding for mixed cultivation and processing will be tested in practice and on the model system wheat-pea.
