摘要
总结我国在中华绒螯蟹形态学、养殖性能、细胞遗传学、生化遗传学及分子遗传学方面的种质研究的主要成果 ,归纳中华绒螯蟹不同种群在形态、细胞、生化、分子等层次上的遗传差异。在形态学研究方面 ,运用形态多元分析 ,建立不同种群绒螯蟹从幼蟹到成蟹的量化判别函数 ;在生化遗传和分子遗传研究方面 ,找到中华绒螯蟹区别于其他绒螯蟹的生化遗传标记和分子遗传标记 ,以及中华绒螯蟹不同种群由南到北的分子遗传渐变标记 ;在养殖性能方面 ,阐明中华绒螯蟹不同种群在幼蟹和成蟹阶段的养殖性能 (包括蜕壳、生长、性腺发育、性成熟及生殖洄游等 )
The auhor summarizes the major results in study on genetic characters of morphology, culture performance, cytogenetics, enzymatic genetics and molecular genetics in Chinese mitten crab (Eriocheir sinensis), including the genetic differences in morphology, cytogenetics, enzymatic genetics and molecular genetics levels. In terms of morphology, the discrimination function to differentiate the morphological traits of different populations of crab is established. In biochemical genetics and molecular genetics aspect, the genetic markers from enzymatic and RAPD profiles are discovered in distinguishing Eriocheir sinensis and Eriocheir japonicus, etc, and the other populations of Eriocheir sinensis. In the culture performance aspect, the variations and characters of growth performances, such as molt, growth, gonad development and spawning migration of different populations are evaluated. A set of discrimination method and technique is established to distinguish the different populations of mitten crab as well as other crabs. Meanwhile, the measures to protect the germplasm resourcs of Chinese mitten crab are put forward.
