摘要：

Zhikong scallop, Chlamys farreri, is the most important species for sea-scallop breeding programs in China. The linkage maps of C. farreri were constructed with AFLP markers generated from 21 primer combinations. The polymorphism level of F1 progeny is 62.94%. Of the 783 polymorphic markers detected, 317 segregated in 1:1 ratios and 190 in 3:1 ratios, whereas the other 276 showed segregation distortion (alpha = 0.05). Linkage analysis used the program MAPMAKER/EXP at LOD = 2.5 and 0 = 0.30. The male map containing 94 markers in 19 linkage groups, was 1511.4 cM in total length and 66.56% in genome coverage. The female map containing 97 markers in 20 linkage groups, was 1610.2 cM in total length and 66.05% in genome coverage. The distribution of AFLP markers is relatively even in chromosomes of male and female map, because only few of clusters were observed.
