Despite their low contents in seeds, protease inhibitors in pea (Pisum sativum L.) have been shown to be important in negatively affecting the performance of pig or poultry. The quantification of these inhibitors by chemical methods is time-consuming and expensive, prompting the development of simple markers to boost progress in breeding programs. Gene polymorphism linked to variation in seed trypsin inhibitor activity has allowed the definition of primers for polymerase chain reaction (PCR) assays, which can be exploited in breeding programs and offer an efficient and cheap pre-screening procedure.
