摘  要:
将灰色综合评判的原理与方法应用于玉米新品种区域试验的分析之中,对2004年国家西北春玉米组区域试验的共13个试点13个参试品种(R312、滑986、冀2518、DH3702、丰试6号、LH02-1、永玉8号、农华105、长城1206、大丰13号、沈试3005、郑试254、沈单16(CK))的9个性状(单穗粒重、生育期、株高、穗位高、穗长、穗行数、秃尖长、百粒重、出籽率)进行了分析,其结果总趋势与联合方差分析的结果相一致,个别品种位次有变动。试验分析得到如下结论:①灰色综合评判方法是传统评价方法的一种直观补充。②灰色关联分析方法简便易行,在育种材料的评价中可以广泛应用。③应根据各地因生态条件和育种目标确定各性状的权重系数。④灰色综合评判方法只对试验所在地生态区域玉米种评价有一定的实际意义。

摘  要:
The principle and method of grey comprehensive evaluafion for crossed combinations were introduced into anbnmaize varieties.The comprehensive evaluation was studied by Data Processing System to 9 agronomic(weight per ear,growth period,plant height,ear position,ear length,row number of kernels per ear,sterile length,100 kernels weight,kernel ratio)characters of 12 varieties(R 312,Hua 986,Ji 2518,DH 3702,Fengsui No.6,LH 02-1,Yongyu No.8,Nonghua 105,Changcheng 1206,Dafeng No.13,Shenshi 3005,Zhengshi 254.Shendan 16(CK)) in Northwest maize regional-test in 2004.Finally the general trend is consistent with the union varianceanalysis result,the individual variety sequence order has the change.The experimental analysis obtains the following conclusion:①grey comprehensive evaluafion is the traditional appraisal method one kind of direct-viewing supplement.②grey correlative degree analysis usesimple is convenient,may widely apply in the breeding materialappraisal.③should act according to each place because theecological condition and the breeding goal determines variouscharacters the weight coefficient.④grey syntheses judgment methodonly to experiments the locus ecology region maize to plant theappraisal to have the certain practical significance.
