Mitotic and meiotic chromosomes of Caryophyllaeus laticeps (Pallas) from Rybinsk reservoir were studied using air-drying techniques. It was established that the diploid set contains 20 metacentric chromosomes. The chromosomes are large--their mean absolute length ranges from 3.00 to 12.90 microns. The last pair of small homologues comprises only 3.4% of the total length of the complement. One specimen of C. laticeps with 2n = 21 (trisomic after the last pair of chromosomes) and one triploid specimen with 3n = 31 is described. Data on the comparative karyology of caryophyllids are discussed.
采用空气干燥技术对来自雷宾斯克水库的宽鳍鲤（Pallas）的有丝分裂和减数分裂染色体进行了研究。结果表明，其二倍体组包含20条中着丝粒染色体。染色体较大，其平均绝对长度在3.00至12.90微米之间。最后一对小同源染色体仅占互补染色体总长度的3.4%。描述了1个2n = 21（最后一对染色体三体）的宽鳍鲤标本和1个3n = 31的三倍体标本。讨论了关于石竹科鱼类比较核型的资料。
