Crossbreeding of chlamys farreri were performed using the parent scallops from the korea wild population ( k ) , china cultured stock ( c ) and the survived individuals in epedimic waters in culture area of china ( cs ) . four crosses , k k , k c , k cs and c c , were constructed . the index of growth performance of their progenies such as the length and width of the shell and the individual weight were measured for heterosis study 用來自韓國野生的櫛孔扇貝和中國養殖的櫛孔扇貝以及發病區存活的個體作為親本，構建韓國野生韓國野生、韓國野生中國養殖、韓國野生中國養殖發病區存活個體以及中國養殖中國養殖共四個交配組合，通過對f1代個體殼寬、殼高和體重的測量比較不同群體的生長情況。
In the study , six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation . the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties . heterosis of spike differentiation was positively correlated with heterosis of hybrid yield . finally , the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region 對6個不同生態類型小麥品種及其完全雙列雜交f1幼穗分化特點和穗分化雜種優勢的研究表明,雜種幼穗分化各主要時期普遍存在雜種優勢；不同生態類型組配方式的雜種穗分化優勢不同；穗分化雜種優勢與產量雜種優勢具有一定相關關系；黃淮麥區雜交小麥最佳生態組配方式為春性品種冬性品種。
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于對對組合和對互（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。
