摘    要:三角帆蚌是我国优良的淡水育珠蚌,具有重要的经济价值。本文从我国三角帆蚌种质资源调查、搜集与保护出发,介绍了三角帆蚌RAPD、SSR及线粒体基因片段等不同分子标记开发状况,重点讨论了这些分子标记分析三角帆蚌遗传多样性的情况。比较了我国五大淡水湖泊三角帆蚌种质及3个优秀种质9个F1后代的生长性能,比较了三角帆蚌雌雄生长差异。简述了三角帆蚌珍珠质形成相关基因、免疫相关基因、贝壳及珍珠颜色相关基因的研究现状。从三角帆蚌与其他蚌类种间杂交、三角帆蚌种内杂交,介绍了培育康乐蚌新品种的过程及三角帆蚌家系选育的进展情况。对今后进一步开展三角帆蚌种质资源研究提出了意见和建议,为三角帆蚌遗传改良提供了基础资料。

关 键 词:三角帆蚌  种质资源  遗传多样性  基因资源  种质创新

Abstract:The freshwater pearl mussel(Hyriopsis cumingii),also known as triangle mussel,is a freshwater bivalve widely distributed in China and is the commercially most important mussel species exploited for freshwater pearl production due to its several advantageous pearl production traits.In the paper,study on the investigation,collection and protection of germplasm resources of H.cumingii,development condition of different molecular markers such as RAPD,SSR and mitochondrial gene were introduced and the application of different molecular markers in genetic diversity research in H.cumingii was discussed.Meanwhile the growth performance of H.cumingii from China's five major freshwater lakes and nine reciprocal hybrids F1 of three excellent germplasm were compared.Then the current research status of pearl formation related genes,immune related genes,shells and pearl color related genes was summarized.And on the basis of interspecific and intraspecific hybridization in H.cumingii,the breeding progress of "kangle" was discussed.Some suggestions for future resarch were put forward,such as using family selection with modern biological technology to breed and promote new varieties which were high yield and quality,meanwhile,study on genome of H.cumingii.This paper provides important scientific basis for genetic improvement of H.cumingii.
Keywords:Hyriopsis cumingii  germplasm resources  genetic diversity  gene resources  germplasm innovation
