Theoretically, our research is founded on the works of Profs. Carolus Linnaeus and N.I.Vavilov.
Nikolai I. Vavilov is recognized as the foremost plant geographer, botanist and geneticist of this age. In the early 20th century, the world was yet unaware of the urgent necessity to protect the environments, and scientists thought little about gradual extinction of plant species. In fact, N.I. Vavilov was the first who understood the imperative of intensive plant collecting, studying and preservation, in spite of the hardest times he experienced in his life.
We have used the special methodology of the Vavilov Institute developed with regard to lupin (Kurlovich et al., 1990b).
Many years of observing plants sown in various regions have enabled us to find out new regularities in the variability of characters depending on genetic features of the species and accessions, and also on ecological and agronomic conditions of their growth.
We have also disclosed new characters and their combinations, both taxonomically significant and genetically determined. This factor as well as generalization of the data obtained by other researchers (Zhukovsky, 1929; Kazimierski and Novacki, 1961; Gladstones, 1974; Maissurjan and Atabiekova, 1974; Kazimierski and Kazimierska, 1975) made it possible to introduce essential corrections in the intra-specific taxonomic and eco-geographic classifications of lupins.
Each form of lupin can be assessed as an object fitting in with a number of consecutive taxa.
A taxon is a part of plant community consisting of a certain set of individual plants distinguished according to genetic principle by the uniformity of their genesis, and regarded as a formal unit at any level of hierarchic classification.
Different species, subspecies, varieties, subvarieties and forms were classified on the basis of Vavilov’s concepts (the law of homologous series in hereditary variation, studies on the problem of the species as a system, differential systematic and geographical method of crop studies, and others).
Vavilov’s (1931, 1965) concept about the species as a complex multilateral and mobile phenomenon implies application of diverse methods for identification of differences between intraspecific categories.
We recognize subspecies (subsp.) as an isolated group of individual plants within a population of a species. They occupy certain part of the area of a species, constitute together a mobile system, are able to cross among themselves and with plants growing in other parts of the area of this species, produce prolific progeny, possess distinctive morphological and inheritable characters in vegetative and generative organs with the uniform genetic base, and incorporate transient forms. (subsp. graecus, termis and albus within the limits of Lupinus albus L.).
Allelism and character complementarity tests have shown that in lupins the color of seed is correlated with the color of the corolla. This linkage reflects the stability of genetic system, which corresponds to the rank of varieties (var.).
A good diagnostic character is the color of vegetative parts, and the absence or presence of anthocyan, in particular. Being less stable, it could be used in identifying subvarieties (subvar.).
Considerable practical interest for breeders may be generated by the plants with determinate branching, fascicular stem and other characters of breeding value. Such forms are theoretically possible in all the varieties and subvarieties systematized by us. Therefore, it seems justified to regard them in the rank of forma (f.) - formae.
