三种分析方法对小麦新品种的综合评判

为对小麦新品种进行综合评价，以10个小麦新品系的主要性状为指标，采用相同的原始数据和权重系数，运用模糊综合评判、DTOPSIS法、灰色关联度分析对其进行综合评判。结果表明，采用DTOPSIS法评判结果为E、A、D三品系综合性状最好，J、F品系最差；灰色关联度分析评判结果为E、D、C、A品系综合性状最好，I、F品系最差；模糊综合评判结果为E、C、D品系为优良品系，H、F品系最差。三种综合评判小麦新品种优劣的顺序虽存在一定的差异，但变化总趋势基本一致，其中综合评判E、D为优良品系，F品系最劣，这与品系的实际表现相一致。

Comprehensive Evaluation of New Wheat Varieties by Using Three Different Analysis Methods

The main characteristics of 10 new wheat strains were analyzed by using the same original basic data and the same weight coefficientions with three different methods of the fuzzy comprehensive evaluation,DTOPSIS and grey system analysis.Results indicated that by DTOPSIS,E,A,D lines were the best,J,F lines were the worst,by the grey system analysis,E,D,C,A lines were the best, I,F lines were the worst,and by fuzzy comprehensive evaluation,the E,C,D lines were the best,the H,F lines were the worst.Some difference exist among results achieved by these three comprehensive evaluation,but their general trends were the same: E,D lines were the best,and F lines was the worst,which were accordanted with actual performance of these.
