  2. 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

    結果表明:對生玉米同互生玉米一樣具有普遍的雜種優勢,在產量性狀上f1對生株優勢互互組合大於對對組合和對互(互對)組合;對生性狀的轉育對產量性狀的一般配合力有降低效應,而含有對生基因的互生玉米具有較高的一般配合力效應,因此,在對生玉米育種中可以利用含有不同對生基因的互生自交系作親本來組配雜交組合(互互) ,從而獲得較高的制種產量和高產的對生雜交種。
  3.
