新疆天山东部平原区引种苜蓿品种的灰色关联度分析与综合评价

Grey correlation analysis and comprehensiveevaluation of introduced alfalfa in easternTianshan plain of Xinjiang

摘要:

通过对新疆天山东部平原区引种的12个紫花苜蓿品种的15个生物学性状利用灰色关联度分析法进行分析与综合评价。结果表明:12个苜蓿品种的15个性状指标中,与干草产量的关联度较高的是平均生长速度、茎粗及叶宽,关联度最小的是粗纤维;12个品种中与标准品种关联度高的品种是WL343、骑士T、拉迪诺3个品种,在新疆天山东部平原区的综合生产性能好,在该区域适宜引种推广;而敖汉、阿尔冈金、甘农三号与标准品种关联度最低,3个品种综合生产性能相对较差,在该区域不适宜引种推广。

Abstract:

Totally 15 biological characters of 12 alfalfa varieties introduced in eastern Tianshan plain of Xinjiang were analyzed and evaluated by grey correlation analysis.The results show that out of 15 biological characters of 12 alfalfa varieties,the highest correlation with hay yield was the average growth rate,leaf width and stem diameter,the lowest was crude fiber content.Among 12 varieties,the varieties with high correlation with the standard varieties were WL343,Knight T and Radino,and their comprehensive production performance was good,which suggested that they were suitable for extension in this area.The varieties with low correlation with the standard varieties were Aohan,Algonquin and Gannon No.3,and their comprehensive production performance was poor.
