摘　　要：利用杂交种的3种组配方式研究其组配效果。结果表明,农大108至今仍是一个适应性广、产量高、性状优良的国家区试对照种。普普单交、普糯单交、普普三交均有可能选育出超级玉米组合。3种方式的组配效果是:普糯单交>普普单交>普普三交。不同生态区超级玉米组合有不同的性状结构。The paper indicates that Nongda 108 still is a fine comparison variety with widely adaptability, high yield and fine character in national regional test. The possible methods to breed heterobeltiosis hybrid maize have General maize inbred × General maize inbred, General maize inbred × Waxy-maize inbred and General hybrid maize inbred × General maize inbred. The effects of three ways to breed heterobehiosis hybred maize are General maize inbred × Waxy maize inbred〉General maize inbred × General maize inbred〉General hybrid maize inbred × General maize inbred. The heterobehiosis hybrid maize has different character structure in different ecology region.
