现代生物育种中,杂交是育种过程中一种重要的手段。所谓“杂交”就是指使不同遗传性的生物的雌雄配子间相互同化的活动过程。人们通过杂交育种方法,获得具有高度生产力的后代,从而取得很大的经济效益。我国鱼类杂交育种活动在五十年代末就受到关注。进入七十年代以后,这一项工作得到了广泛开展。在这期间,共进行了60多个杂交组合的试验,其中成功的最有声誉的要算鲤鱼品种之间的杂交。我们在兴国红鲤杂交和雌核发育等育种工作中也取得一定的成效,其中杂种一代有“丰鲤”、“芙蓉鲤”和异精雌核发育产生的子代“异育银鲫”(以下简称银鲫),在生产中已得到推广,养殖效果颇佳,普遍增产,反映良好,很受欢迎。 In modern biological breeding, crossbreeding is an important method in the breeding process. The so-called “hybridization” refers to the activity of the interaction between the male and female gametes of different hereditary organisms. People obtain highly productive offspring through hybrid breeding methods, thus achieving great economic benefits. China’s fish breeding activities in the late fifties attention. After entering the seventies, this work has been widely carried out. During this period, a total of more than 60 hybrid combinations were tested, of which the most successful of the successes were the crosses between common carp varieties. We also made some achievements in breed breeding such as crossbreeding and gynogenetic development of red carp in Xingguo. Among them, the hybrids have “Feng carp”, “Furong carp” and offspring “allogynogenetic crucian carp” Hereinafter referred to silver crucian carp), has been promoted in production, breeding is quite good, generally increase production, reflecting the good, very popular.
