Аннотация: Results of karyological study of Picea ajanensis (Lindl. et Gord.) Fisch. ex Carr examined from 13 provenances are presented. In addition to the cytotypes with typical chromosome number (2n = 24), P. ajanensis displays cytotypes with one or two B-chromosomes (2n = 24 + 1 - 2B). Among A-chromosomes, there are 8 pairs of long metacentrics and 4 pairs of shorter meta- or submetacentrics. Among B-chromosomes there are two types of chromosomes: metacentric (B1) and submetacentric (B2) ones. There are many nucleolar chromosomes. Several chromosomes have secondary constrictions. Patterns of B-chromosome distribution within P. ajanensis are have been discussed.
