本文应用多元分析法对河北省1981至1989年的棉花抗病品种(系)区域试验结果进行了分析。分析结果表明,最优参试品系的产量因素结构最佳,其皮棉产量最高;在产量因素结构预测方面,能够满足预测标准的参试品系具有最佳产量因素结构,可获得最佳产量水平。
In this paper, the regional test results of cotton resistant varieties (lines) from 1981 to 1989 in Hebei Province were analyzed by multivariate analysis. The results showed that the yield components of the best tested lines had the best structure and the highest lint yield. In terms of the structure prediction of yield factors, the tested lines that could meet the prediction criteria had the best yield structure and the best yield level.
