| 摘 要： | 以抱卵雌虾的受精卵、眼点明显可见的胚胎以及雄虾精巢为材料,空气干燥法制备染色体,进行秀丽白虾的细胞遗传学研究.结果显示,秀丽白虾胚胎细胞染色体数目2N=90,核型组成是2N=56M 8SM 12ST 14T,染色体总臂数NF=154,染色体数略少于长臂虾属和沼虾属,但核型组成相似.

| Abstract: | A cytogenetic study was conducted in the freshwater prawn,Exopalaemon modestus,and the meiotic and mitotic chromosomes were obtained by modified air-dry method applied to the oosperm,embryo cells and testis.The microphotography assay showed that the chromosome number of the prawn was 2N=90,the karyotype 56M 8SM 12ST 14T,the total number of chromosomal arms(NF) 154,and chromosome number less than those in the prawns Palaemon and Macrobrachium's. |

| Keywords: | Exopalaemon modestus haploid chromosome karyotype |
