皱纹盘鲍的遗传育种研究进展

Advances in genetics and breeding in Haliotis discus hannai:a review

皱纹盘鲍为我国北方的重要养殖品种,但随着养殖规模与密度的不断扩大,因种质退化等原因导致暴发性病害频发。因此,皱纹盘鲍的遗传改良研究对于皱纹盘鲍养殖产业的可持续健康发展十分重要。本文对我国皱纹盘鲍(Haliotis discus hannai)的生物学特征、微卫星标记、选择育种、杂交育种、多倍体育种、雌核发育的研究现状进行了综述,并对今后皱纹盘鲍遗传育种的方法和方向作了展望。

Halioti., discus hannai is an important economically shellfish speices in nouthern China. However, with the expansion of the culture scale and increasing of density,fulminant disease followed by germplusm degration frequently. Therefore, genetic improvement plays an important role in sustainable development for Haliotis discus hannai aquaculture industry. The paper summarizes the recent progress in biologica characteris- tics,selective breeding, crossbreeding, SSR makers, gynogenesis. The further reseach directions in these topics were also proposed.
