早在1984年， rossignac和requicha就提出用滾球法進行過渡曲面的設計，但用這種方法得到的曲面表達式比較復雜，而且在滾球半徑較大時容易出現自交的現象。F2 the second filial generation, obtained by crossing or selfing within the f1 generation
子二代（雜種二代） ： ，通過子一代內部的雜交或自交獲得。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。Reviews on heterotic group partition of maize inbred lines
