【摘要】 采用完全双列杂交试验，对６个玉米自交系组配成的１５个单交种的单株粒重配合力和花培出愈率配合力进行了研究。结果表明，在６个自交系中京４３８０的单株粒重一般配合力（ｇｃａ）最高，出愈率的ｇｃａ较高，而Ｂ６７０的单株粒重ｇｃａ最低，但出愈率的ｇｃａ却很高；单株粒重的ｇｃａ与出愈率的ｇｃａ两者不呈正相关；京４３８０×Ｂ６７０这一单交种在１５个杂交组合中出愈率最高，花培反应最强。因此在进行玉米花培育种时，如果选用含有出愈率ｇｃａ较高的亲本自交系的组合作材料，会有较高的出愈率，有可能培育出高配合力的花培系。更多还原

【Abstract】 The combining ability of grain weight per plant and the combining ability of callus induction frequency have been studied among 15 single cross hybrids which were combined with 6 maize inbred lines by means of the diallel crossing system.The results show that both Jing4380 and B670 have high general combining ability of callus induction frequency, so Jing4380 X B670 has the best anther culture response, i. e. the highest callus induction frequency among 15 single cross hybrids. In order to breed maize inbred lines by anther culture, the combinations inbred lines of higher GCA of induction frequency must be adopted.更多还原
