经纬杂交试验分析新法──最优线性无偏预测

NEW METHOD FOR ANALYSING TWO-WAY NETWORK CROSSES ──Best Liner Unbiased Prediction

对于经纬杂交试验，首次引入了最优线性无偏预测原理。提出了一种新的分析方法，并就数学模型、统计假定、方差组分估计及具体求算各个步骤进行了深入细致的研究．这种方法假定各参数为随机效应，不受重复数等与不等的影响，且可以剔除环境效应，并利用多环境下的资料，因而可以提高预测值的准确性并使其具有更广泛的适用性．

A new method for analysing two-way network crosses was proposed, which was based on the essential idea of BLUP.The mathematical model, statistical hypothesis,the estimation of variance components and the solutions of them were studied in detail.The method can get rid of the environmental effects and use data got from multi-environments.So it can increase the accuracy of prediction and iseasible in a wide range.
