- Abstract
Data on supernumerary or B chromosomes in some species of the Picea (Spruce) genus are presented. Many species of this genus contain B chromosomes in the karyotypes and are convenient objects for studying their origin and role in conifers. So far, B chromosomes have been found in 23 Picea species including the interspecies hybrid P. ×fennica. The number of B chromosomes per cell varies from one to six. Spruce species contain meta- (B 1 type) or submetacentric (B 2 type) Bs. The results obtained allow to conclude that B chromosomes may be of adaptive significance in the evolution of the genus Picea species
