Abstract: WISH-ROOTS (Wheat Improving Soil Health through Root traits) is an interdisciplinary project aiming to identify wheat root traits to improve nitrogen use efficiency and soil health, including microbiome diversity & functions as well as soil physical properties. The morphological and functional root traits of wheat landraces can conserve and improve the targeted soil health markers. Introducing these beneficial traits into modern, high-yielding wheat cultivars might contribute to sustaining and restoring agricultural soils for future yield production. Bread wheat and durum wheat lines contrasting in root architecture, inhibition of nitrification rate, or soil characteristics have been chosen. Theseselected lines and their effect on the surrounding soil are being analysed in parallel field trials conducted by the seven partners and in controlled environment experiments.The 20 selected lines were grown in rhizotrons in the new rhizotron facility of Forschungszentrum Jülich, GrowScreen-Rhizo III. This platform allowed daily imaging of shoot and root system, and watering to weight. The plants were grown in a mixture of peat soil and field soil from the field trial station. At harvest, shoots, roots, and rhizosphere soil for microbial analysis were collected. Initial analysis of root growth showed large differences between bread and durum lines, including seedling vigour and root growth rate being larger in durum wheat lines. In addition, within bread and within durum lines differences were found concerning total root length, root angle, and lateral root formation. Subsequent rhizotron experiments will contain more genotypes allowing first time phenotyping of dozens of landraces. (EJP-SOIL project WISH-ROOTS, Förderkennzeichen 031B1263)
