Despite their low seed contents, vicine and convicine in faba bean (Vicia faba) and protease inhibitors in pea (Pisum sativum) are important feed constituents because of their negative effect on pig and poultry performance. The chemical determination of these compounds is time-consuming and expensive. We have developed simple markers to boost progress in breeding. In faba bean, the gene controlling hilum colour maps a small distance from the gene determining the seed vicine and convicine content and this phenotypic trait can therefore be used as a marker. In pea, gene polymorphism linked to variation in seed trypsin inhibitor activity (TIA) has allowed the definition of primers for polymerase chain reaction (PCR) assays, which can also be exploited in breeding programs. In both cases, these markers offer an efficient and cheap pre-screening procedure.
