Distant hybridization refers to the cross between two different species or higher-ranking taxa. It is very significant if the new lineages with genetic variation, fertile ability, and improved characteristics can be established through distant hybridization. However, reproductive barriers are key limitations that must be overcome to establish fertile lineages derived from distant hybridization. In the present review, we discussed how distant hybridization is an important way to form new species by overcoming reproductive barriers and summarized effective measures to overcome reproductive barriers in order to create fertile lineages of fish distant hybridization. In addition, we described the utilization of the fish lineages derived from distant hybridization. Finally, we discussed the relationship between distant hybridization and Mendel's laws, which generally apply to the inbred hybridization. We aim to provide a comprehensive reference for the establishment of fertile fish lineages by overcoming reproductive barriers and to emphasize the significance of fish distant hybridization in the fields of evolutionary biology, reproductive biology and genetic breeding.

通过克服远距离杂交建立可育鱼类谱系

远距离杂交是指两个不同物种或更高级分类群之间的杂交。如果能通过远缘杂交建立具有遗传变异、可育能力和特征改良的新谱系，意义重大。然而，生殖障碍是必须克服的关键限制，以建立源自远缘杂交的可育谱系。在本综述中，我们讨论了远缘杂交如何成为克服生殖障碍形成新物种的重要途径，并总结了克服生殖障碍的有效措施，以创造鱼类远缘杂交的肥沃谱系。此外，我们描述了来自远距离杂交的鱼类谱系的利用。最后，我们讨论了远缘杂交与孟德尔的关系 s 定律，通常适用于近交杂交。我们旨在通过克服生殖障碍为建立可育鱼类谱系提供综合参考，并强调鱼类远缘杂交在进化生物学、生殖生物学和遗传育种领域的意义。
