Mediterranean White Lupin Landraces as a Valuable Genetic Reserve for Breeding

Legumes crops are important for sustainable agriculture and global food security. Among them white lupin (<i>Lupinus albus</i> L.), is characterized by exceptional protein content of high nutritional value, competitive to that of soybean (<i>Glycine max</i>) and is well adapt...

Among them white lupin (<i>Lupinus albus</i> L.), is characterized by exceptional protein content of high nutritional value, competitive to that of soybean (<i>Glycine max</i>) and is well adapted to rainfed agriculture. However, its high seed-quinolizidine alkaloid (QA) content impedes its direct integration to human diet and animal feed. Additionally, its cultivation is not yet intensive, remains confined to local communities and marginal lands in Mediterranean agriculture, while adaptation to local microclimates restrains its cultivation from expanding globally.
