运用DTOPSIS法对鲜食甜玉米新品种在浙西北地区适应性的综合评价

摘要

以浙江省建德市生产上应用较普遍的鲜食甜玉米品种浙甜2088为对照(CK),采用DTOPSIS法对11个鲜食玉米种的11个性状进行了综合评价.按照DTOPSIS法Ci值结果,品种综合评价顺序为:浙甜218＞浙甜811＞浙甜11＞浙甜318＞先甜90＞浙甜2088 (CK)＞浙甜214＞浙甜815＞浙甜817＞Thps1＞嵊科甜208,浙甜218、浙甜811、浙甜11、浙甜318、先甜90,这5个品种的综合农艺性状优于对照.浙甜218因其产量突出,品质优良,生育期、株高适中,在综合评价中表现最好,可在建德等浙西北地区进行重点推广示范,浙甜811、浙甜11、浙甜318、先甜90表现优于对照,可在浙西北地区进行一定规模的鲜食甜玉米示范种植.%Taking the commonly-cultivated fresh-eating sweet corn variety Zhetian 2088 in Jiande city as the control (CK),we comprehensively evaluated the 11 characters of 11 fresh-eating sweet corn varieties introduced in this city by adopting DTOP-SIS method.According to the Ci values (comprehensive evaluation scores) calculated by DTOPSIS method,the tested sweet corn varieties were arranged as follows:Zhetian 218＞Zhetian 811 ＞Zhetian 1 1＞Zhetian 318＞Xiantian 90＞Zhetian 2088 (CK)＞Zhetian 214＞Zhetian 815＞Zhetian 817＞Thps1＞Shengketian 208.The comprehensive agronomic characters of 5 varieties including Zhetian 218,Zhetian 811,Zhetian 11,Zhetian 318 and Xiantian 90 were better than those of the control.Because of high yield,good quality,and proper growth duration and plant height,Zhetian 218 had the best performance in this comprehensive evaluation,and this variety can be emphatically popularized and demonstrated in the northwestern areas of Zhejiang.The performance of Zhetian 811,Zhetian 11,Zhetian 318 and Xiantian 90 was better than that of the control,and these 4 varieties can be demonstratively planted in a certain scale in the northwestern areas of Zhejiang.
