摘要: 利用大样本镜鲤繁殖群体分析和验证8个生长相关微卫星标记与体质量和体长的相关性。结果显示:8个微卫星标记在镜鲤繁殖群体中均获得了稳定、清晰的DNA条带,片段大小在100~322 bp之间,共检测到33个等位基因、75种基因型。对每个微卫星座位的基因型与体质量、体长性状进行相关性分析发现,HLJ343与体质量、体长显著相关;HLJ319、HLJ302及HLJE339与体长显著相关。本研究用大样本随机群体证实了此4个QTL位点与体质量或体长性状具有相关性,下一步可根据优势基因型指导家系配组,开展基于QTL结果的分子聚合育种研究。

Abstract: Correlation between Genotypes of eight microsatellite loci and growth trait was analyzed and verified using mirror carp breeding population with large samples. Steady and clear DNA bands were amplified in 8 microsatellite markers with the size ranged from 100 to 322 bp. Thirty-three alleles and 75 genotypes were detected. The correlation was analyzed using data of body weight, body length and genotypes. The results show that HLJ343 had a significant impact on body weight and length. In addition, there were three loci, HLJ319, HLJ302 and HLJE339, and they had a significant impact on body length. This analysis reveals that the 4 QTL loci had correlation with body weight and length in large samples of mirror carp. Next, it can guide the breeding program according to the dominant genotype. And then, the researches in molecular marker assistant breeding selection will be carried out based on the QTL results.

Key words: microsatellite marker, body weight, body length, Cyprins carpio L.
