摘要

本研究的目的是通过常规方法(Giemsa, c -带和Ag-NOR染色)确定土耳其Rhodeus amarus (Block, 1782)的染色体特征。从头肾细胞中获得中期染色体。二倍体数为48，基数为76。染色体形态上分别为4对、10对和10对。c带出现在大多数染色体的中心周围区域，在银色染色中期观察到单个AgNOR。这一结果可能会扩大对苦鱼染色体特征的认识。

Karyology of Rhodeus amarus (Block, 1782) (Teleostei, Acheilognathidae) from Turkey

The aim of this study was to determine chromosomal characteristics of Rhodeus amarus (Block, 1782) from Turkey by conventional procedures (Giemsa, C-banding and Ag-NOR staining). Metaphase chromosomes were obtained from the head kidney cells. The diploid number was found as 48 and the fundamental number as 76. Chromosomes were morphologically characterized as metacentric (four pairs), submetacentric (10 pairs) and subtelo-acrocentric (10 pairs). C-bands were found to occur on the pericentromeric regions of most of the chromosomes and a single AgNOR was observed on Silver stained metaphases. The results may expand the knowledge on chromosomal features of bitterlings.
