摘　　要：黄鳍棘鲷是我国东南沿海重要的海水经济鱼类,是目前尚没有通过国家原良种审定委员会审定的新品种。为做好黄鳍棘鲷新品种选育工作,培育出生长速度快的新品种,需估计生长性状的遗传力。本研究以黄鳍棘鲷为研究对象,采用巢式设计和人工授精方法,构建了19个黄鳍棘鲷全同胞家系(包括7个半同胞家系),测量35日龄黄鳍棘鲷的生长数据,并使用MTDFREML软件对其全长进行遗传力估计。结果表明,35日龄黄鳍棘鲷全长的遗传力为(0.234±0.047),属于中等水平遗传力。研究结果可为黄鳍棘鲷的良种选育提供参考资料。Acanthopagrus latus is an important marine economic fish in the southeast coast of China.At present,there is no new breed approved by the National Original Breeds Approval Committee.In order to breed a new variety of A.latus with fast growth,it is necessary to estimate the heritability of growth traits.In this study,nineteen full sibling families of A.latus including 7 half-sib families were constructed by using the nested design with an artificial insemination.The growth data of 35-day-old A.latus were measured,and their full-length heritability was estimated using MTDFREML software.The results showed that the heritability of full length was(0.234±0.047),which was moderate.The results provide reference materials for the selection breeding of the A.latus in the future.
