Potential for breeding white lupin for calcareous rich soils in the Netherlands

Summary in the original language of the document

White lupin (Lupinus albus) can be an interesting crop for both organic and conventional farmers who are looking for leguminous crops to broaden their crop rotation scheme. Lupin is also of interest for food processors as a guaranteed GMO-free protein source for the replacement of soy. However, the available varieties ripen too late in the Netherlands. Furthermore, the largest areas suitable for arable farming are calcareous rich clayey soils. So, there is a need for early maturing calcium tolerant varieties. The goal of this study was a broad evaluation of lines of white lupin for suitability for cultivation on clayey soils high in calcium content, in order to determine whether there is sufficient perspective for further breeder for both conventional and organic farming in the Netherlands.
