The overarching goal of the "LinSel" project is to provide farmers with lentil genotypes (Lens culinaris L.) that are well-adapted to Central European conditions. This research aims to increase yield, yield stability, and quality, thereby expanding the cultivation of the lentil legume. As part of the project, genotypes will be identified, selected, further developed, and tested to achieve optimal adaptation for farming systems in Germany, thus establishing the lentil as a "new" old crop. Cultivation beyond the traditional growing regions is also a key focus. The project's results have the potential to expand the product range for breeders, farmers, and consumers by introducing a legume cash crop, particularly useful in resource-efficient mixed cropping systems and organic farming. The project is coordinated by the Center for Organic Farming, at the University of Hohenheim. Project partners include the Institute of Crop Science, University of Hohenheim, along with the departments of General Crop Production and Quality of Plant Products, the Leibniz Institute of Plant Genetics and Crop Plant Research, Genebank Department, the Keyserlingk Institute, and the Department of Organic Plant Breeding and Agricultural Biodiversity, University of Kassel.
