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
