应用灰色关联分析法评价全国南方区花生新品种区域试验

摘要

应用灰色系统理论中的灰色关联分析法，对参加2010年全国南方区花生新品种区试的13个花生品种进行综合定量分析评价。结果表明，泉花551和参考品种间的关联度最大（r1=0．7838），其次是航花2号（r2=0．7098），汕油250第三（r4=0．6934），闽花9号第四（r3=0．6933），莆花23第五（r6=0．6891），这5个品种的综合评价均优于对照汕油523（r9=0．6765）。%The relational grade analysis of the grey theory was adopted in multifactorial quantitative evaluation of 13 new national peanut variety regional trail in Southern China in 2010. The results showed the relational grade between Quanhua 551 and the reference variety was the first （r1 = 0. 7838）, Hanghua 2 was the second （r2 =0. 7098）, Shanyou250 was the third （r4 =0. 6934）, Minhua 9 was the fourth （r3=0. 6933）, and Puhua 23 was the fifth （r6 =0. 6891）, these five varieties were all better than the control Shanyou 523 （r9 =0. 6765）.
