摘要： 将6个玉米群体完全双列杂交所得到的群体及群体间杂交种在3个地区进行试验，采用Gardner和Eberhart的ANALYSISⅡ和Ⅲ对性状进行分析，结果表明，许白群产量vj最高，hj最低，均达极显着水平，gj中等；洛孟综产量vj和hj较高，gj最高；二南24群产量vj较高，hj较低，gj略高。这3个群体综合农艺性状较好，应进行特殊配合力的轮回选择，洛孟综可用于选育自交系。BSSS产量vj最小，hj最大，gj中等，抗病性和适应性差，应采取混合选择。许黄群2和新群2号表现较差，不宜继续改良。BSSS×二南24群产量和杂种优势较高，可作为相互轮回群体改良

Abstract: Six maize populations and their hybrids produced in a complete diallel mating scheme were evaluated at 3 locations. Characters were analysed under the model of ANALYSISⅡ  Ⅲ of Gardner  Eberhart. The results showed that Xubai population had highest yield vj(P<0.01),lowest hj (P<0.01)and middle gj; Luomeng synthetic had highest yield gj,higher vj and hj; Ernan 24 population had higher yield vj and gj,lower hj.The three populations had good agronomic characters,and they should be further improved for SCA.Luomeng synthetic can be used for selecting inbred lines.BSSS,with lowest yield vj,highest hj,middle gj and lack of disease resistance and adaptability,should be further improved through mass,selection.Both Xuhuang population and Xin population No.2 should not be further improved because of their had performances. The cross of BSSS×Ernan 24 population,with higher yield and heterosis,can be used as recurrent selection populations for further improvenent.

Key words: Maize, Complete diallel cross, Population, Recurrent selection
