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，可作为相互轮回群体改良 The results showed that the yield of Xu Baiqun was the highest and the lowest was hj, both of which were tested by Gardner and Eberhart’s ANALYSIS II and III Reached extremely significant level, gj medium; Luo Meng yield vj and hj higher, gj highest; two south 24 group yield vj higher, hj lower, gj slightly higher. The three groups are better agronomic traits, should carry out special combining ability of the cycle of choice, Luocheng comprehensive can be used for breeding inbred lines. BSSS yield vj minimum, hj maximum, gj medium, disease resistance and poor adaptability, should be taken to choose a hybrid. Xu Huang group 2 and the new group 2 poor performance, should not continue to improve. The yield and heterosis of BSSS × Ernan 24 group were higher, which could be used as the reincarnation groups
