通过对我国五大淡水湖泊三角帆蚌近3年的评价,筛选出生长性能好、抗病率强、育珠性能佳的三角帆蚌优良种质。项目组运用传统的评价技术结合现代生物技术查明了我国洞庭湖、鄱阳湖、太湖三个地理种群的三角帆蚌具有较好的经济性状。这三个种质纯度高、优良性状表现明显,较浙江当地的人工养殖蚌生长速度快15-25%,珍珠蚌的成活率提高30%-50%,产珠率提高20%左右。

    Through 3 years estimation research, good germplasm of triangle sail mussel (Hyriopsis cummigii) was successfully obtained in China Five Largest Fresh Water Lakes. The Triangle sail mussel strain is charactered with quick growth speed, strong anti-disease, and significant growing characters.
    Comparative study was conducted on the morphology, growth and molecular genetics of geographic populations of (Hyriopsis cumingii) in China’s Five Large Lakes and Zhuji cultured population. The application of tradition technology and combinative modern bio-technique to the research, researchers found out the Dongting Lake, the Poyang Lake and the Taihu Lake , these geographical population triangle sail mussel had a very obviously economic advantage in practice. After 3 years of estimation, these triangle sail mussel strains are very pure in gene, with obvious phenotype than native artificial farmed mussel in Zhejiang(a province in China). In growth speed, these stain is 15-25% quicker than native artificial farming mussel in Zhuji, 30%-50% more living rate, 20% more production rate.
