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。

Abstract:

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.

Key words: Acanthopagrus latus, family, full length, heritability
