文献[1]提出综合杂种优势概念及经纬杂交试验设计中综合杂种优势的 BLUE和置信区间;但把各配合力效应都视为固定效应,所得结论只能推断试验本身.为从同一经纬杂交试验获得更多信息,本文把各配合力效应视为随机效应,据混合线性模型理论,给出了经纬杂交设计中综合杂种优势的BLUP,可预测某品系与任一品系杂交的效果.本文还讨论了综合杂种优势的经济生物学基础,提出了确定目标性状及其相对经济价值的原理和方法,为实践中正确使用综合杂种优势的理论和方法奠定基础.
The literature [1] proposed the concept of integrated heterosis and the BLUE and confidence interval of the integrated heterosis in the hybrid design of latitude and longitude. However, the effects of combining forces are regarded as fixed effects, and the conclusion can only infer the experiment itself. For more information, this paper treats the effect of combining force as a random effect. According to the mixed linear model theory, BLUP, which provides comprehensive heterosis in longitude and latitude hybrid design, can be used to predict the effect of hybridization between a certain line and any line. Based on the economic and biological basis of comprehensive heterosis, the principle and method of determining the target traits and their relative economic value are put forward, which lays the foundation for the theory and method of correctly using comprehensive heterosis in practice.
