| 摘 要： | 对合浦珠母贝12个全同胞家系的生长性状和才女虫寄生病的感染情况进行比较分析,结果显示:筛选出的快速生长家系F10、F11、F3和F12与生长最慢的家系F7相比,壳高分别大16.01％、14.93％、10.51％和10.16％,体质量分别重35.72％、28.02％、25.98％和17.61％.筛选出的抗病家系F8、F9、F11和F10,其才女虫寄生病的总感染率与感染最高的家系F3相比,分别降低了48％、34％、27％和23％,表明这4个家系初步提高了合浦珠母贝抗才女虫寄生病的能力.筛选出的快速生长家系和抗病家系可作为选育的核心育种家系,为培育生长速度快和抗才女虫寄生病的合浦珠母贝新品系奠定良好的基础.

| Abstract: | In this study, the wild Pinctada fucata from Sanya, Shenzhen and Vietnam were used as brood stock
to construct 30 full-sibs families, and the polychaetes infection of 12 families with higher survival were analyzed. The
selected families of F10, F11, F3 and F12 showed rapid growth, and the shell height improved by 16.01%, 14.93%,
10.51% and 10.16%, and the body weight improved by 35.72%, 28.02%, 25.98% and 17.61% compared with family
F7 with the slowest growth. The families of F8, F9, F11 and F10 had the lowest polychaetes infection, and decreased
by 48%, 34%, 27% and 23% compared with family F3 with the highest infestation. It demonstrated that the above 4
families improved the polydoraiosis resistance preliminarily. Those selected families could be used as the core
breeding population for improving polydoraiosis resistance of P. fucata. In addition, the results also provided a
reference for cultured P. fucata with selecting fast growth and polydoraiosis resistance. |
