利用16个小麦亲本及其双列杂交的120个F1为材料研究了亲本性状表现、一般配合力、特殊配合力及杂种优势间的关系,结果表明:各性状杂种优势与特殊配合力均存在极显著正相关;如果亲本一般配合力效应中含有较高的杂种优势效应,即使组合的特殊配合力较低,也有可能表现较强的杂种优势;若双亲一般配合力效应中杂种优势效应都较低,即使该组合特殊配合力较高,也难以表现明显的杂种优势。强优势组合选配应在亲本高一般配合力的基础上选择高特殊配合力组合。
The relationships among the traits of parents, general combining ability, special combining ability and heterosis were studied using the data of 120 F1 progenies of 16 wheat parents and their double crosses. The results showed that there were both heterosis and special combining ability in each trait . If the parental general combining ability effect had higher heterosis effect, even if the combination’s special combining ability was lower, it might show stronger heterosis; if the parental combining ability effect had lower heterosis effect , Even if the combination of special combining ability is high, it is difficult to show obvious heterosis. Strong combination of superiority should be based on the parent’s high general combining ability to choose a high combination of special combining ability.
