[目的]研究滁州鲫、方正银鲫及彭泽鲫间的分子遗传差异。[方法]滁州鲫、方正银鲫和彭泽鲫为我国3个不同地区的三倍体银鲫种群,用9对引物对它们进行了RAPD分析。[结果]9对引物中,仅引物P10扩增的产物没有差异外,其余8种引物(P1～P8)的扩增产物均有一定的差异。[结论]3个不同地区的银鲫种群在基因水平上存在一定差异,在遗传相似性方面,滁州鲫与方正银鲫的相似性较大,滁州鲫与彭泽鲫的相似性则较小。
[Objective] The research aimed to study the molecular differences between Chuzhou crucian carp, Founder silver crucian carp and Pengze crucian carp. [Method] Chuzhou crucian carp, Founder silver crucian carp and Pengze crucian carp were three populations of Triploid silver crucian carp in three different regions in China. Nine pairs of primers were used to analyze them by RAPD. [Result] Among the 9 pairs of primers, there was no difference between the products amplified by primer P10 alone and the amplified products of the other 8 primers (P1 ~ P8). [Conclusion] The genetic diversity of crucian carp crucian carp was different in three different regions. The genetic similarities between Chuzhou crucian carp and Founder silver crucian carp were similar, while the similarity between Chuzhou crucian carp and Pengze crucian carp was smaller.
