荷元鲤(荷包红鲤 Cyprinus CarpioVar.Wuyuanensis ♀×元江鲤 C.Carpioyuankiang♂)具有明显的杂种优势,业经原国家水产总局主持鉴定。为了进一步提高荷元鲤的生长性能,改良某些经济性状,探讨鲤鱼性状遗传的规律,我们进行了荷元鲤与视本荷包红鲤及元江鲤的回交育种试验。本文报道了荷元鲤与视本回交子代(荷元鲤回交鱼或称回交鲤)的形态特征,特别是与生长和产量有密切关系的体型特征及其与视本的关系,为鲤鱼性状遗传规律的研究及育种实践,提供了资料。同时,三年多的生产性试验证明,荷元鲤与元江鲤的回交鱼,较
The lotus carp (Cyprinus CarpioVar.Wuyuanensis 荷 × Yuanjiang carp C.Carpioyuankiang♂) has obvious heterosis, the industry by the former State Fisheries Administration presided over the identification. In order to further improve the growth performance of lotus carp, improve some economic traits, and explore the genetic rules of carp traits, we conducted a backcross breeding test between lotus carp and its own purse red carp and Yuanjiang carp. In this paper, we report the morphological characteristics of the common carp (Hylobates carpio L.) and its backcrossing offspring (Hylobates carotis or the backcross carp), especially their body characteristics closely related to growth and yield, Carp genetic characteristics of genetic law and breeding practice, provided information. At the same time, more than three years of production tests show that the Yuan carp and Yuanjiang carp backcrossing fish, compared
