以青鱼(Mylopharyogodon piceus)为母本和三角鲂(Megalobrama terminalis)为父本的杂交虽是不同亚科的远缘杂交,但有正常的受精细胞学程序和常规的细胞分裂<卵裂>方式。这些实验结果,为开展鱼类远缘杂交提供了受精生物学的理论基础;同时还证实鱼类远缘杂交的异种精子不仅有激活卵子的作用,而且参与了遗传物质的组成,使父本的性状能够在杂种后代表现出来。实践证明,鱼类遗传育种可以通过远缘杂交的途径获得杂种优势。青鲂杂种一代既具有母本青鱼的性状,也兼有父本三角鲂的特征,通过养殖试验已在渔业生产中取得成效<拟另文发表>。
Although the crossbreeding of Mylopharyogodon piceus and Megalobrama terminalis is the distant hybridization of different subfamilies, there are normal fertilization cytology programs and conventional methods of cell division. These experimental results provide the theoretical basis for the fertilization biology for the distant hybridization of fish. At the same time, it is also confirmed that the heterologous sperm hybridized by distant fish not only has the effect of activating eggs, but also participates in the composition of genetic material, Traits can appear in the hybrid offspring. Practice has proved that fish genetic breeding can obtain heterosis by means of distant hybridization. Barley hybrid generation has both the characteristics of the mother of herring, but also with the characteristics of the father of the Triangle, through aquaculture trials have been made in the production of fisheries.
