摘　　要：本文报道了近江牡蛎（ＯｓｔｒｅａｒｉｖｕｌａｒｉｓＧｏｕｌｄ）担轮幼虫期染色体制各方法及核型分析结果．近江牡蛎２Ｎ＝２０，ＮＦ＝４０，均为中央着丝粒染色体．另外，还观察了近江牡蛎核型的多态现象．A method of obtaining enough metaphase Chrmosomes for karyotype analysis from trochophora of Ostrea rivularis was eatablished. The diploid number of Ostrearivularis is 20. Its karyotype formula is 20m , but subtelocentric chromosmes and sat-chromosomes (bearing satellite bodies) were occasionally recongnised. This polymorphism ofkaryotype of Ostrea rivularis was disscussed.
