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，均达极显著水平，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。
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.
