【摘要】 利用彭泽鲫Carassiusauratusvar.Pengsenensis作母本、黑龙江野鲤Cyprinuscarpio作父本进行不同属间的远缘杂交,获得的杂交一代(F1)杂种优势明显。利用1#催产剂(HCG800IU/kg+LRH-A23μg/kg)进行人工催产,催产率为93%～100%,受精率为64 0%～75 4%,孵化率为81 7%～82 0%;将杂交鲫与双亲的生物学性状进行比较,杂交鲫与彭泽鲫相似(用数理统计中的独立性检验X2=0 075,X20 05=9 49,X2<X20 05,P>0 05,差异不显著);对杂交鲫与双亲的乳酸脱氢酶同工酶(LDH)进行测定,杂交鲫与母本鲫的LDH酶谱相似。更多还原

【Abstract】 Intergeneric hybrids of Carassius auratus var. Pengsenensis (♀)×Cyprinus carpio (♂) had high heterosis. Goldfish and common carp broodstock were induced to spawn by hormone injections of 800 IU HCG/kg +3 μg LRH-A2/kg body weight, resulting in spawning rate of 93%～100%, fertility rate 64.0%～75.4%, and hatching rate 81.7%～82.0%. The hybrid F1 is simlar to goldfish (X2=0.075, X20.05=9.49, X2< X20.05, P>0.05, through X2 test) in morphology and lactic dehydrogenase (LDH) compared with their parents.更多还原
