摘要
以纯种方正鲫作母本、以方正鲫(♀)与鳞鲤(♂)交配获得的雌性后代经性反转的生理雄性个体作父本进行育种试验,在3个组配中,发现有一组F_1表现出新的形态特征。经过对F_1及其后代作定向培育和观测,证实F_1形态指标与方正鲫差异显著,且其后代遗传性状稳定,可作为鲫鱼属的一个新品系。
Breeding experimerts were carried out, with purebred Fangzheng crusian carp as the
female parent, and the sex-reversed progenies, produced by Fangzheng crusian (♀) ×scaled carp
(♂), as the male parent. of the 3 mating groups, F_1 of one mating group were found to manifest new
morphological characters. After the oriented breeding of F_1 and their progenies, observations confirmed
thesignificant differences of their morphological indices from those of Fang zheng crusian and the sta-
ble hereditary features of their progenies, thus, F_1 and their progenies can be taken as a new strain of
carassius.
