AFLP ANALYSIS OF MOLECULAR MARKERS RELATED TO GROWTH TRAITS IN CYCLINA SINENSIS
青蛤(Cyclina sinensis)生长性状相关分子标记的AFLP分析

In this paper, 60 mixed breeding offsprings from two natural populations of Cyclina sinensis were used to screen molecular markers related to shell length, shell width, shell height and body weight under the method of AFLP and one-factor analysis of variance. The results showed: of detected 18 gene loci related to shell length, the contribution rates were between 6.46% and 18.32%, and the contribution rates of E32M51-8, E33M51-38 were higher, respectively 18.32% and 15.68%. The contribution rates of detected 23 gene loci associated with shell width were between 6.75% and 20.93%, and those of E32M51-8, E33M48-19 were higher, respectively 20.93% and 17.34%. For shell height, 22 associated gene loci were detected, their contribution rates were between 6.54% and 15.91%, and the E32M51-17 locus had the highest contribution rate. Eight gene loci related to body weight were analyzed, the highest contribution rate (locus E33M48-10) was 17.83%, and lowest value was 6.65%.
