Abstract: In Germany, grains of the pseudocereal buckwheat (Fagopyrum esculentum Moench) used to be a staple food, until it was nearly completely replaced by higher yielding cereals in the past century. Nowadays, buckwheat is increasingly valued for its gluten-free nature and health-promoting secondary metabolites such as rutin. As a low input crop with short cultivation time, it is also suitable to be cultivated as second crop even under dry summer conditions. To re-establish buckwheat production in Germany, the project BIMOTEC investigates genotypic and phenotypic variability in buckwheat as a prerequisite for breeding local, climate-resilient cultivars with high grain yield. In addition, BIMOTEC aims to unravel the bioeconomic potential of buckwheat as a multi-purpose crop for the extraction of secondary metabolites from leaf biomass and seed hulls, as well as bio-based platform compounds from stem biomass. BIMOTEC will develop modern breeding technologies and perform extensive pre-breeding involving phenomics, transcriptomics, and metabolomics. We particularly focus on the genotypic variation in phenotypic development and secondary metabolism in response to drought. The novel high-throughput plant phenotyping platform GrowScreen-Rhizo III will be used to assess root and shoot growth dynamics of a large number of cultivars from a global buckwheat panel to identify favorable root and shoot traits and stress tolerant genotypes. Metabolite profiling and gene expression studies of plants grown under control and drought conditions will further reveal breeding targets for climate-resilient buckwheat cultivars with high bioeconomic potential. Buckwheat production in Germany will further be facilitated by the development of improved agronomic models for yield under drought. Through our interdisciplinary approach, we will reveal new drought tolerance traits for buckwheat and promote breeding of local buckwheat cultivars.
