Protein crops are important for a modern and sustainable agriculture that has to cope with the transition to a bioeconomy and is confronted with the consequences of climate change and biodiversity loss. We are therefore investigating a new cultivation system in which flowering plants grow between the soybean rows and thus increase biodiversity without significantly affecting the yield or quality of the soybeans. To this end, various flowering plants are being tested for their suitability and their effect on the soil microbiome. In addition, soybean lines with good tofu properties are being tested on a control and on selected flowering plants in the new Citizen Science project. This will be complemented by multi-site field trials in which the new cultivation system will be evaluated and the genotype-environment interaction of agronomic traits, tofu traits and omics predictors will be investigated. In addition, QTL mapping will be carried out to investigate the genetic architecture of tofu traits. One focus of the industrial partner Taifun is the optimization of tofu production for further processing into tofu-based products. Overall, the project will support the establishment and optimization of tofu products and is an important first step to investigate the genetic aspects of a new farming system that has the potential to increase biodiversity in our agricultural systems, for higher consumer acceptance and a sustainable bioeconomy.
