`Dear authors of the Wikipedia entry about Lupinus mutabilis. I am a student in the master course ``alternative crops`` at the ETH Zurich. Part of this course was an update of a Wikipedia entry of our choice. Below you can find the modified entry. I am happy about all kinds of feedback and comment. -     Lupinus mutabilis is a species of lupines grown in the Andes, mainly for its edible bean. Vernacular names include tarwi, tarhui, chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, or pearl lupin.Lost crops of the Incas: little-known plants of the Andes with promise for worldwide cultivation / report of an ad hoc panel of the Advisory Committee on Technology Innovation, Board on Science and Technology for International Development, National Research Council. - Washington, D.C.: National Academy Press, 1989, page 180-189. There are different aspects why L. mutabilis could become an important international crop. But until now, the high content of alkaloids in the seed is the main reason, why the crop is not very known outside the Andes. This content could be decreased by different processes.   == Origin and Dissemination ==  The origin of L. mutabilis has been identified in the Andean region of Ecuador, Peru and Bolivia.Neglected crops: 1492 from a different perspective / ed. by J. E. Hernández Bermejo and J. León; publ. in collab. with the Botanical Garden of Córdoba (Spain) as part of the Etnobotánica 92 Programme (Andalusia, 1992). - Rome  Food and Agriculture Organization of the United Nations, 1994. In this area, the greatest genetic variability in the world was found.The plant has been domesticated for more than 1500 years, mostly because of its high protein content.  == Biology ==  L. mutabilis is an annual plant. The steam is hollow and highly branched. Plant height reaches from 0.5 to 2.80 meters, depending on the environmental conditions and the genomic properties. Due to the high vegetative growth, species from northern South America are taller than species from the southern Andean region.

The genome contains 2n = 48 chromosomes and there is a high genomic variation, which leads to big differences in morphology. Several architectural types of L. mutabilis exist. Most common is the branching in V-form, this type has the highest biomass production. The basal branching type has the positive feature that its infructescence is at the same level. This species is preferably promoted because of its early ripening, stability and the homogeny seed quality.  Morphology  The fruit is a 5-12 cm long pod, depending on the amount of seed. One pod contains on average 2-3 seeds, but can have up to 9 seeds per pod. The thousand-seed weight (TSW) is around 200g. Leaves are palmate and have a typical appearance: one leave is divided in five to twelve leaflets, which have an oval or lanceolate form. The form is typical for Faboideaes. The corolla reaches 1-2 cm and contains five petals. Variation in coloration is high and reaches from white to purple. The white coloration is recessive to purple. L. mutabilis has a strong taproot reaching 3 m length. Like all Leguminosae secondary roots build nodules containing bacteria for nitrogen fixation.  Development  The growing cycle varies from 150 to 360 days, depending on the genotype, altitude and environmental conditions. Phenological phases are: emergence, first true leaf, formation of the raceme on the central stem, flowering, podding, pod ripening, and physiologica
