摘要: 研究采用混合线性模型,对家蚕全茧量、茧层量、茧层率和蛹体重等性状的性别效应进行理论估算:全茧量、茧层量、茧层率和蛹体重等4性状的性别随机效应的方差的概率和性别随机效应的预测值概率都达到极显著水平,证明全茧量、茧层量、茧层率和蛹体重等四性状的性别效应极显著,这完全符合实际情况。全茧量、茧层量、茧层率和蛹体重等4性状的性别效应预测值雌(雄)分别为0.248g(-0.247g)、2.423cg(-2.394)cg、-1.976%(1.992%)和0.224g(-0.223g)。性别效应调整后各性状均呈单峰正态分布,符合QTL分析对数量性状连续正态分布的要求。

Abstract: In this paper , the sex-effects of the cocoon quality characters in silkworm was predicted with Mixed linear model :The fact that the probability of effect variance and predictability of random gender of whole cocoon weight, cocoon shell weight, ratio of cocoon shell and pupa weight reached a level of extreme significance showed that the gender effect of the four traits was extremely significant, which matched with the reality completely. The predictive values of gender effect of the four traits of female(male) were 0.248g(-0.247g)、2.423cg(-2.394)cg、-1.976%(1.992%)和0.224g(-0.223g) respectively. Each trait showed single peak distribution after adjusting by sex-effects, which fitted for the request that quantitative traits should show continuously normal standard distribution if QTL analysis was taken.
