灰色决策在花生品种布局中的应用效果

根据品种目标,运用品种单目标灰色布局的方法,对2002和2003年鲁西南地区花生品种区域比较试验结果的产量、倒伏率、叶斑病病指、枯萎病病指、病毒病病株率、锈病病指、生育期7个性状进行综合分析,求得参试品种的综合效果测度矩阵,最后比较其综合效果测度值,可发现在b1(泰安市)、b2(济宁地区)、b3(菏泽地区)、b4(枣庄地区)环境下分别以L02-1、丰花5号9、9166、丰花5号表现最好,其综合效果测度值分别为0.119 80、.113 70、.112 20、.105 4,明显高于其他品种的综合测度值。通过试验研究,找出了各环境区域最适宜种植的花生品种,为花生新品种布局提供决策依据。

Analysis of Application Effect on Grey Decision in Distribution of Peanut Varieties

According to the target of variety,based on the results from the peanut variety region comparison test in southwest area of Shandong in 2002 and 2003,7 traits of yield,the lodging ratio,leaf spot disease index,blight disease index,viral disease plant rate,rust disease index and growth period were analyzed synthetically by method of single target grey distribution of variety.The measurement matrixes of synthetic effect on participated varieties were calculated and the measurement values of synthetic effect were compared then.Results showed that L02-1,Fenghua 5,99166 and Fenghua 5 in b1(Taian area),b2(Jining),b3(Heze area) and b4(Zaozhuang area) circumstances had best exhibition,with the measurement values of synthetic effect being 0.119 8,0.113 7, 0.112 2,0.105 4 correspondingly,which were higher than those of other peanut varieties.The optimum peanut varieties that were suitable for planting in all kinds of areas were found in this test,which supplied to decision-making on distribution of new peanut varieties.
