利用赤拟谷盗作为试验动物，设计不同群体大小的选择群，基于动物模型估计的育种值对赤拟谷盗23 d蛹重双向选择6个世代，分析遗传参数与选择反应的变化趋势。结果表明：所有选择群体获得了不断增高的估计育种值，没有获得对称的表型值蛹重的选择反应；选择群体蛹重现实遗传力的估计均获得中等或高的估计值，范围在0．25～0．56；基础群动物遗传结构、选择群体的大小、世代效应、选择方向是影响遗传参数估计与选择反应的主要因素，基于动物模型估计育种值选择可获得持续、稳定的选择反应。

Based on estimated breeding value of pupa weight of Tribolium Castaneum by individual animal model,Tribolium Castaneum populations with different sizes were divergently selected for 6 generations for estima-tion of genetic parameters and evaluation of response to selection .Results suggested that constant progress of esti-mated breeding value in all selected populations were achieved ,the response to selection of pupa weight was asym-metrical,and the realized heritability was in a range of 0.25-0.56;The genetic structure of base population ,popu-lation size ,generation ,selection direction could be important factors affecting estimation of genetic parameters and selection progress;selection progress could be obtained based on breeding value by animal model .
