Teza

Introduction A distinctive feature of the spikelike types of the blue lupine is the absence of branching in the top part of the main stem and the formation of the pods on the main stem both on the cluster and under it - in the leaf axils instead of the lateral branches, whereupon the generative sphere becomes similar to the ear of cereals. The authors also use the terms “epigonal mutants” and “highly restricted branching” to describe such morphotypes. [1-4]. Material and methods The morphological and taxonomic description of 29 spikelike samples of L. angustifolius L. from VIR collection was being conducted in the fi eld conditions of Moscow region according to a list of descriptors [7] and intraspecifi c classifi cation [4-6] annually in 2009-2011. Results and discussions As a result of the morphological descriptions and their comparison with the diagnostic features of species, subspecies and forms we have found that the existing intraspecifi c classifi cation of L. angustifolius L. best refl ects and systematizes the intraspecifi c diversity represented in the VIR-collection, but needs to include the amendments. We reported previously about our remarks [8]. The taxonomic characteristics have been assigned to 27 samples on the results of morphological descriptions and taking into account the amendments. One sample (k-3365 Determinant 2, Russia) is a new determinant form into species Var. albopunctatus Kurl. et Stankev. Two samples (k-3639 Bryansky 1298, Russia and k-3501 L-300, Poland) have been attributed to Var. purpureus Kurl. et Stankev. The assignment of subspecies for this samples is problematic since the presence of the anthocyanin on the cotyledons in combination with the green color of the vegetative organs are characteristic for this samples but is not inherent for any of subspecies. We need to conduct a reconciliation of descriptions of the subspecies subvar. purpureus and subvar. rhodanthus Kurl. et Stankev. with the appropriate diagnostic samples for solve this problem. Conclusions 1. The additions to the description of the diagnostic features of species and subspecies have been incorporated into the existing intraspecifi c classifi cation of Lupinus angustifolius L. The taxonomic position of 27 samples have been found. 2. A new form Var. albopunctatus Kurl. et Stankev f. spicatus Vlas. f. nova, which is absent in the existing taxonomy have been discovered in the process of studying of the samples. 3. There are two samples Var. purpureus Kurl. et Stankev. (k-3639 Bryansky 1298, Russia and k-3501 L-300, Poland), which was unable to establish a subspecies.
