一、2005年以前 (一)建立5种主要水产养殖动物:鲤鱼、草鱼、对虾、扇贝和罗非鱼的DNA水平的遗传连锁图谱并将生长、抗寒、抗病等数量性状基因定位在连锁图上。 (二)改进鱼虾贝类的染色体倍性操作技术,提高成活率,建立四倍体与普通二倍体交配获得大量三倍体的技术路线,培育出3-5种多倍体鱼、贝和雌核发育鱼、贝;构建罗非鱼全雄性群体和对虾全雌性群体,获得2-3种雌性纯合系或单性养殖群体;
I. Prior to 2005 (a) Establishment of a genetic linkage map of the DNA levels of five major aquaculture animals: carp, grass carp, shrimp, scallop and tilapia and the mapping of quantitative trait genes such as growth, cold resistance and disease resistance On the map. (B) to improve the fish prawn shellfish ploidy operation techniques to improve the survival rate, the establishment of tetraploid and diploid mating to obtain a large number of triploid technology line to cultivate 3-5 kinds of polyploid fish, shellfish And gynogenetic fish and shellfish; constructing whole tilapia population and whole female population of prawn and obtaining 2-3 female homozygous or uniparental breeding groups;
