应用灰色关联分析评价南方区春花生新品种

Multi-factorial Evaluation of New Spring Peanut Varieties in South by the Methods of Gray Relational Grade Analysis

采用灰色系统理论的关联度分析方法,对13个南方区春花生新品种的10项主要指标进行了综合评价。结果表明,湘花120与理想品种的关联度最好(r1′=0.8786),粤油29次之(r2′=0.6853),粤油13(r3′=0.5994)第三,这3个品种均优于汕油523(r5′=0.5992)。综合评价结果与品种在2003、2004两年的品种比较试验中的表现基本一致。

Mathematical method of the relational grade analysis of the gray theory was applied to multi-factorial evaluation of 10 main index of 13 new spring peanut varieties in south. The results showed that the relational grade between Xianghual20 and the reference was the first （r1＇=0.8786） , Yueyou29 was the second （r2＇=0. 6853） , Yueyou1 3 was the third （r3＇ = 0. 5994）. these 3 cultivars were all better than Shanyou523 （r5＇ = 0. 5992）, The results of multi-factorial evaluation was basic consistent with performance of variety test.
