| Abstract: | Twenty-one microsatellite markers were selected to investigate the genetic diversity of two Takifugu rubripes Populations from T.rubripes Quality Fish Farm(Japanese Population and Qinhuangdao Population).The number of effective alleles(Ne) of two populations were 3.3697,2.8593,respectively,the value of expected heterozygosity(He) on two populations were 0.6516,0.6073,respectively and the mean polymorphism information content(PIC) were 0.6009 and 0.5509,respectively.The results suggest that two populations were on high level of genetic diversity,providing useful information for genetic improvement and selective breeding.Linkage analysis has been conducted with the genotypes of 21 microsatellite loci and body weight,body length and body height of 96 individuals from Japanese population,suggesting that maker f161 and f273 had a significant impact on body weight(P<0.05),maker f170 and f501 had a significant correlation of body length(P<0.05) and maker f53 and f331 had a significant impact on body height(P<0.05).In addition,four genotypes of these correlative markers were determined. |
