齐口裂腹鱼(Schizothorax prenanti)与金沙鲈鲤(Percocypris pingi)杂交F1代胚胎发育观察及早期生长研究
Observation of Embryonic Development and Early Growth of F1 Hybrid between Schizothorax prenanti and Percocypris pingi
摘要
Abstract
[Objective]This study aimed to clarify whether the hybrid offspring have normal growth and development,using a crossbreeding was conducted between Schizothorax prenanti and Percocypris pingi.[Method]This study cross the Schizothorax prenanti with the Percocypris pingi hybridization obtained the orthologous progeny group(SP),the reciprocal progeny group(PS),and the self-seeding group of S.prenanti(SS).The developmental characteristics of hybrid offspring embryos were observed and re-corded,and their fertilization rate,hatching rate,abnormality rate,survival rate and growth perfor-mance were analyzed.[Result]The hatching rates of the SP group and the PS group were(16.67±6.66)%and(15.67±2.31)%,which were significantly lower than those of the SS group(P<0.05).At 91 days of age,the survival rates of the SP group and the PS group were 22%and 14%,respectively,which were significantly lower than those of the SS group(P<0.05).The abnormality rate was about 33%in the SP group,whereas it was as high as 90%in the PS group.The body weight and full length of the PS group were significantly lower than those of the SP and SS groups(P<0.05).[Conclusion]This experiment demonstrated for the first time that S.prenanti and P.pingi can be distantly hybridized,of which the SP group can grow and develop normally.关键词
