• The results indicated that opposite maize had widespread heterosis like alternative maize ; yield advantage of opposite f1 ( alternative alternative ) was better than that of f1 ( opposite opposite ) and f1 ( alternative opposite or reverse ) ; general combining ability of yield characters was decreased by opposite characters transfer maize , but alternative maize with opposite genes has high general combining ability , so that on the opposite maize breeding , alternative inbred lines with different opposite genes can be parents for breeding hybrid lines ( alternative alternative ) and hybrid varieties with more seeds and high yield can be obtained
  结果表明：对生玉米同互生玉米一样具有普遍的杂种优势，在产量性状上f1对生株优势互互组合大于对对组合和对互（互对）组合；对生性状的转育对产量性状的一般配合力有降低效应，而含有对生基因的互生玉米具有较高的一般配合力效应，因此，在对生玉米育种中可以利用含有不同对生基因的互生自交系作亲本来组配杂交组合（互互） ，从而获得较高的制种产量和高产的对生杂交种。
