摘　　要：为挖掘和拓宽贵州优良玉米种质资源,利用5个贵州玉米地方品种为父本,中国农业科学院提供的8个热带玉米改良群体为母本,按NCⅡ设计组配,对其配合力进行研究。结果表明:贵州玉米地方品种中册亨Suwan黄包谷和地33综合性状的一般配合力高,8个热带玉米改良群体中中群11、中群24和中群27综合性状的一般配合力高,40个杂交组合中中群27×册亨Suwan黄包谷、中群26×地33,中群23×地33,中群11×平塘黄包谷,中群22×马场小黄包谷,中群28×吊南早,中群25×平塘黄包谷,中群22×地33,中群23×平塘黄包谷,中群11×吊南早等组合具有较强的特殊配合力,可进一步组建新的群体和选择优良自交系。The combining ability of 5 local maize varieties from Guizhou and 8 tropical maize improvement populations ♀ provided by Chinese Academy of Agricultural Sciences was determined by NCⅡ design to explore and broaden good maize germplasm resources in Guizhou. Results： The general combining ability of Ceheng Suwan Huangbaogu and Di 33 from Guizhou and Zhongqun 11,Zhongqun 24 and Zhongqun27 populations from Chinese Academy of Agricultural Sciences is high. Zhongqun 27 × Ceheng Suwan Huangbaogu,Zhongqun26 × Di33,Zhongqun23 × Di33, Zhongqun11 × Pingtanghuangbaogu, Zhongqun 22 × Machangxiaohuangbaogu, Zhongqun28 × Diaonanzao,Zhongqun25 × Pingtanghuabaogu,Zhongqun22 × Di33,Zhongqun23 × Pingtanghuabaogu and Zhongqun11 × Diaomamzao combinations from40 hybridized combinations with the higher special combining ability can be used to innovate new populations and select good inbred lines further.
