温州光唇鱼与半刺厚唇鱼双列杂交子代胚胎发育及生长特性
Embryonic development and growth characteristics of diallel hybrid progeny of Acrossocheilus wenzhungensis and A.hemispinus
摘要
Abstract
[Objective]The embryonic development and growth characteristics of hybrid offspring of Acrossocheilus wenchowensis(WW)and A.hemispinus(HH)were explored to provide a basis for the cross-breeding and selection of high-quality varieties of Acrossocheilus.[Method]A.wenchowensis and A.hemispinus were utilized as parental species for diallel hybridization,resulting in the formation of or-thogonal group(WH),reciprocal cross group(HW),and inbred groups(WW and HH).The embryonic development characteristics of the offsprings were observed,with analyses on the fertilization rate,hatching rate,and larval growth performance across the 4 exper-imental groups.[Result]Some surviving orthogonal and reciprocal cross offsprings were obtained,and their embryonic development showed certain characteristics of maternal inheritance.There were differences in the order of eye lens formation stage and muscular re-sponse stage between fertilized eggs with different female parents.The fertilization rates of both hybrid combinations were significantly higher than that of the 2 inbred combinations.The hatching rates of both hybrid combinations did not differ significantly from that of HH group,yet markedly higher than that of WW group.The early growth rates of hybrid progenies showed biased paternal characteris-tics,and were lower than that of WW group.After cultured for 120 d,the hybrid offsprings were higher in fatness than those of inbred groups,but had no mid-parent heterosis in body weight and full length.[Conclusion]A.wenzhungensis and A.hemispinus could be suc-essfully crossed,and the growth rate of the reciprocal cross group was higher than that of maternal inbred group.关键词
