Abstract:'itm comprehensive evaluation of nine new super—sweet corn varieties from the regional test in Fujin praovince was
conducted by grey correlative degree analysis according to the data of their fourteen traits including plant height,yield and SO on As
a result,the multi—characters of several COFgl varieties such as Jinyinsu 2,Chaotian 2000,Guangtian 2,Mintian 208 were better than
those of Suitian 1(CK).The evaluation results were consistent with the actual performance.
Key words:Super—sweet corn;Grey correlative degree;Comprehensive evaluation
灰色关联分析法是邓聚龙教授1982年创立的一种重要统计分析方法。这种方法的基本思想是根据所研究的因
子问变化的相似程度来判断关联度,关联度愈大说明因素问变化态势愈接近,其相互关系愈密切。本文试用灰色关联
度分析法,在以往对超甜玉米区域试验新品种进行产量、品质、抗病虫性、抗逆性和稳产性等单项指标进行定性分析和
比较的基础上,对福建省21304年超甜玉米区域试验的9个参试品种(系)的株高、穗位高、双穗率、穗长、穗粗、秃尖、穗 行数、行粒数、鲜穗重、百粒重、出籽率、采青日数、品质、产量等14项性状进行综合评价,进一步提高评定结果的准确
