In Germany, the faba bean is still a little common field crop; By 2016, the acreage increased to about 40,500 ha. Main causes are among other things their susceptibility to dehydration and the presence of anti-nutritive seed constituents: Tannine and vicine and convicine limit the use of faba bean as feed for non-ruminants. Only a few vicine- and convicine-poor (e.g., Tiffany) varieties of summer faba bean have been developed, moreover vicine- and convicine-poor winter faba beans do not exist. The breeding of vicine- and convicine-depleted varieties is impeded, because no suitable rapid screening tool for the selection of low vicine/convicine content exists and because a gene- or marker-based breeding selection is not implemented. Our goal, together with our project partners, is to analyse the genetics of vicine- and convicine-poverty and to find closely linked markers for the targeted breeding of new winter faba beans that are attractive for agriculture.
