Abstract

Abstract: In this paper, karyomorphologically studies were carried out on five species of Primula.The results were as follows. The number and karyotypes of metaphase chromosomes were formulated to be 2n=2x=18m for P. forbesii，2n=2x=20m+2sm forP. secundiflora Franch, 2n=2x=20m+2M for P. sinensis，2n=2x=22m for P. maximowiczii， 2n=2x=22m for P. serratifolia. The karyotypes were all of 1A type exceptP. sinensis which the karyotype was 1B type.The karyomorphology of four species, P. forbesii, P. sinensis, P. maximowiczii, P. serratifolia were reported for the first time.

Key words: Primula, Chromosome, Karyotype
