以优良玉米杂交组合南２１－３×８１５６５为材料，经选株连续多代单株自交分离选择，育成了自交系２８６－４。对该系主要经济性状的一般配合力进行了测定，并与国内近年常用的骨干系进行了比较，表明２８６－４主要经济性状的一般配合力都接近或超过了国内优良自交系水平。用该系已组配的杂交组合，有３个在各级区域试验中表现很好，说明２８６－４具有较广阔的应用前景。
With excellent maize hybrids south 21-3 × 81565 as materials, the inbred lines 286-4 were bred by the selection of multiple inbred lines. The general combining ability of the main economic traits was measured and compared with the commonly used skeleton traits in recent years in China. The results showed that the general combining ability of the main economic traits of 286-4 were close to or exceeded the domestic good inbred lines. Three lines of hybrid combinations that had been assembled with the line performed very well in the regional experiments at all levels, indicating that 286-4 has a broader application prospect.
