连续几年栉孔扇贝大面积死亡现象严重制约了北方贝类养殖业的发展 ,造成了巨大的经济损失。栉孔扇贝和虾夷扇贝生物学性状差异较大 ,可望通过杂交途径培育出抗逆性强、生长快的扇贝养殖新品种。杨爱国等[1] 和周丽青等[2 ] 的研究结果表明 ,栉孔扇贝与虾夷扇贝正反交杂交子一代 In recent years, the widespread death of scallop scallop has severely restricted the development of shellfish farming in northern China, resulting in huge economic losses. Chlamys farreri and Scallop scallop biological characteristics of the larger differences, is expected to crossbred ways to cultivate strong resistance, fast growing scallop breeding new varieties.
