Abstract

|
|
A karyotype of cytotype BB plant in Scilla scilloides complex was established and the frequency of B-chromosomes were investigated. Chromosome complements of BB genome were composed of five pairs of subtelocentric and four pairs of metacentric chromosomes. Chromosome 1 has satellite with nucleolar organizer. Polymorphism was found in chromosome 2. The karyotype of cytotype BB will be available for analysis of genome composition in various cytotypes of S. scilloides complex. The frequency of B-chromosome was 38.6%. Numbers of B-chromosome ranged from 1 to 4 and plants with 2B-chromosomes were predominant (57.2%). Two types of B-chromosomes, F and F´, were found; F is large iso-chromosome and F´ a small one.
