摘要:Twelve waxy maize varieties (including the control varieties)in 1 3 test points of Huang-Huai-Hai waxy maize region were comprehensive evaluated by grey correlative degree analysis.The results showed that the grey comprehensive evaluation method could be used as a intuitive supplementary method of the pooled variance es-timate and high and stable coefficient analysis,which could not limit the sample size and could be used for compre-hensive evaluation of many varieties.‘Jingcai sweet-waxy’due to the highest correlation of the quality,ξi(k)=1 , moderate bald tip,the higher correlation of the fresh ear yield,ξi(k)=0.846 4,mature period short,smaller residue ratio (%)and higher lodging resistance,ξi(k)=0.955 7,and other excellent qualities,this results was consistent with the certification requirements of waxy corn variety,and it had passed the national examine and approve.The application of comprehensive evaluation of grey system theory was used in waxy corn varieties,it was scientific and practical significance for the area to guide introduction and promotion new variety.Jing waxy 5 1 8 had the highest correlation,0.837 4,‘Lang waxy No.2’had the highest weighted correlation degree,0.902 0,however,both of them were not conducive to the industrialization and popularization of waxy corn processing,because of their quality and lodging resistance were poor.Furthermore,selected weight coefficient and related traits for comprehensive eval-uation were the key influence to the results.In conclusion,grey system theory calculation method was simple,which directly provided quantitative indexes for the comprehensive evaluation of varieties.%利用灰色关联度分析法,对2011年国家黄淮海糯玉米区域试验点的12个糯玉米参试品系(含对照)进行综合评判.结果表明:灰色综合评判方法可作为联合方差,高稳系数分析方法的直观补充,可以不限样本量,多品系比较.‘京彩甜糯’由于其品质关联度最高ξi(k)=1,秃尖适中,鲜穗产量ξi(k)=0.8464较高,并且具有熟期短、皮渣率较小,抗倒伏系数高ξi(k)=0.9557等优良品性,符合目前糯玉米品种审定的要求,已通过国家审定推广;灰色系统理论应用于糯玉米参试品种的综合评价,对指导地区引种、推广具有一定的科学性和实际意义.‘景糯518’的等权关联度最高,为0.8374,‘锒糯2号’的加权关联度最高,为0.9020,但是二者的品质性状太差,倒伏率较高,不利于糯玉米产业化和推广加工;权重系数的判定和相关性状的选定对结果的影响比较关键;灰色系统理论计算方法简单,可为品种的综合评价提供更直接的量化指标.
