Introductions were made to Oxford, England, of a number of strains of the pearl lupin (Lupinus mutabilis Sweet) from South America. In the first season of growth, two of these strains showed considerable promise for development as a field crop in England. Analysis of the seeds confirmed that they are comparable to the soya bean in their content of protein and oil. The chief disadvantage of the species is that the seeds contain toxic alkaloids. Alkaloid-free strains of this species have twice been bred in the past; the seed of these strains has been lost, but such work could be done again. (It is regretted that there is no surplus seed available for distribution from Oxford at present.)
