| 摘 要： | 品种是影响玉米高产的主要因素之一,不同区域选择适宜的品种对玉米高产有着重要意义.针对云南省保山市隆阳区品种混杂多样、农民盲目选种等特点,2013年保山市隆阳区农业技术推广所（玉米区域推广站）对26个玉米新品种进行展示试验,采用灰色关联度分析法对26个展示种的12个性状进行综合分析评价.结果表明：云瑞506综合性状最好（ri=0.6991）,其后依次为云瑞68 （ri=0.0.6804）、云瑞2号（ri=0.0.6480）、云瑞3号（ri=0.0.6178）和云瑞668（ri=0.6032）,靖丰6号（ri=0.4165）综合性状较差.依据综合评价结果,选择适宜保山市隆阳区种植的玉米新品种,为农民选择优良品种提供科学依据.

| Abstract: | The variety is one of the main factors affecting maize yield, so choosing suitable variety is a way to obtain the high-- yielding in different areas. In view of the various cultivars and farmer select seed aimless in Longyang, Baoshan, Longyang agricultural technologye extension station （maize regional extension station） demonstrated 26 new maize varieties. The grey correlative degree analysis was applied to analyzed and comprehensively evaluate the growth performance of 26 maize varieties by 12 characteristics. The results showed that Yunrui506 is the best variety （ri=0. 6991）, followed by Yunri68 （ri=0. 0. 6804）, Yunri2（ri=0. 0. 6480）, Yunri3（ri=0. 0. 6178） and Yum＇i68（ri=0. 6032）,Jingfeng6 （ri=0. 4165） is the worst variety. Based on the comprehensively evaluate results, by choosing suitable variety in Longyang, which could provide scientific basis for lamer in selecting of qualified maize seeds. |
