ProFaba: Developing improved Vicia faba breeding practices and varieties to drive domestic protein production in the European Union.

ProFaba aims to boost protein production in Europe by improving faba bean (Vicia faba) as a European protein crop, thereby contributing to a more balanced and protein-self-sufficient agricultural system. The project brings together experts in a variety of fields to tackle the main obstacles to faba bean success as a protein crop. Using a collaborative approach focusing on common resources, ProFaba will build a common reference and data repository for faba genome, genotype, and phenotype data, ensuring easy communication throughout the faba community. These resources will be leveraged by developing common diversity panels and breeding lines, phenotyped for agronomic traits in five European locations. This will allow deciphering the genomic architecture of faba traits, understanding genotype by environment interactions, and direct incorporation of this knowledge into active, predictive breeding programs through the participating breeders from Denmark, Germany, France and Spain.

ProFaba provided funding to Stig U. Andersen and was funded by the European Union's Horizon 2020 research and innovation program under grant agreement No [771134]. 2019 – 2022

NORFAB: NORthern FABa

NORFAB (NORthern FABa) is a consortium of Northern hemisphere groups with key expertise in Faba beans who aim to develop sophisticated genomics-based plant breeding methods and provide access to germplasm with the relevant genetic diversity. NORFAB aims to improve the yield and quality of faba bean seeds in order to make them a competitive protein crop in northern European and Canadian/US northern prairie conditions. Research on Faba bean genomics and genetics will be developed using new genotyping and phenotyping methodologies and new hybrid approaches combining genomic selection with QTL mapping and gene introgression. The methods for genomics-based breeding will be developed by the university partners and implemented by the industry partners involved in the project. The approach will target multigene control of seed quality, content of protein, fiber and antinutritional factors along with agronomical traits.

The NORFAB project provides funding to Stig U. Andersen and Jens Stougaard through an  Innovation Fund Denmark Grand Solutions grant, 2016-2021.

NCHAIN: Forging stronger links in the organic nitrogen chain.

In agriculture, nitrogen (N) is an important macronutrient critical for plant yield. Without access to synthetic N fertilizers, many Danish organic farmers face a severe challenge in providing sufficient amounts of nitrogen for optimal crop yield. The main N contribution often comes from clover/grass swards, which both generate feed for livestock and provide N fertilization and soil improvement for successive crops in a crop rotation scheme. The N chain in this production system has four main links: 1) Symbiotic N2 fixation by rhizobia; 2) Transfer of fixed N to legume hosts (clover); 3) Transfer of fixed N to other plant species (grasses); 4) Transfer of plant N to cattle. Overall, the efficiency depends heavily on interspecies interactions between rhizobium/clover and clover/grass. The state of the art is to assume that rhizobia already present in the soil provide effective nitrogen fixation with all clover varieties: essentially, that genetic variation between rhizobia is insignificant or that optimal rhizobia for all clover varieties are present in all soils. In terms of plant interactions, it is assumed that the performance of clover and grass varieties determined in monoculture reflects their performance as mixed crops. We hypothesize that gains in N fixation and biomass yield can be obtained using genomic prediction of interspecies interactions, and we will test this hypothesis by capturing and analyzing genotype and phenotype data for rhizobium/clover/grass crops.

NCHAIN provided funding to Stig U. Andersen and was funded by the Innovation Fund Denmark, 2015 – 2020.
