Abstract: Lupinus mutabilis Sweet is an Andean protein crop with agro-economic potential. However, it is characterized by low yields and phenotypic plasticity related to environmental conditions when cultivated in different locations in Europe. Current research objective was to evaluate L. mutabilis agro-morphological performance in two locations in Greece and to record its pollinators, since these can contribute to optimization of crop performance. For this purpose, eight Andean lupin accessions, one white and one blue lupin commercial varieties were evaluated for 71 agro-morphological traits in a Randomized Complete Block design with three replications. Combined Analysis over Location presented a significant accession-location interaction for traits of economic interest such as seed crude protein and 100 seed weight. Seed crude protein was higher in L. mutabilis accessions (up to 43.8 g 100 g −1 seed) than white and blue lupins. Andean lupin yielded up to 327 kg ha −1 (LIB214) in Kalamata, while its yield was lower than the white lupin in Athens. Using principal component analysis, three groups of accessions were formed, one by each lupin species and three within Andean lupin accessions. Floral traits such as color and size are related to pollinators diversity and preference. Insect pollinators and floral traits interplay among different lupin species was examined. Pollinators visited L. mutabilis flowers belong to the genera Anthophora , Bombus , Megachile and Xylocopa . The results of the present study, indicate that L. mutabilis has agronomic potential and enhances above ground biodiversity, however breeding for higher yields is required.
