摘要
运用准主成分方法结合加权方法对甜叶菊9个品种作2种综合评价，该方法不仅提供避免信息重叠的综合评估指标，寻找可测的几个关键因素，还可通过分类加权方法，分辨甜叶菊产量与品质两类综合指标在选种时所起的作用，运用线性规划进行品种寻优。
In this paper, The method of quasi principal component and giving weight is used for 2 types of compositive evaluation of 9 breeds of rebaudiana,given an indicator of compositive evaluation that avoid the cross information,and found several critical factors . The method of giving weight distinguishs the role of output and quality of rebaudiana for the seed selection. The linear programming is used for seeking the improved variety of rebaudiana.
