The genus Lupinus , numbering some hundreds species of different age and origin, is a perfect object for studying the genetic bases of evolution, plant speciation and phylogenies of plants.
It is possible to make conclusions about the tendencies in the domination of characters, their change, ways of adaptation and evolution of plants in the course of time and under the effect of limiting factors, comparing the degree of development of different characters in the species contrasting in their origin and age.
The conducted studies and generalizations helped to formulate answers to the most important questions of plant introduction and breeding, i.e. what kind of genetic diversity should be collected and where, as well as what should be utilized and for what purpose.
We have made a small attempt to contribute to the classifications of lupins. Our developments certainly demand specification, addition, perfection, and maybe revisions. We will, however, remark that our classifications are recognized in many countries and used by scientists and plant breeders.
In summary, it should be mentioned here that the genus Lupinus L. is still waiting for researchers who could find out the true number of species and their intraspecific taxa within this polymorphous genus on the American continent. It will help to clarify many theoretical and practical issues.
