| 摘 要： | 用亲本为15和20个玉米自交系的两组双列杂交试验资料，以双列杂交鉴定配合力的结果为标准，研究了骨干系配合力在测交试验中的表现。结果表明：5个骨干系测交法的鉴定结果准确性差，不能用来鉴定自交系的配合力。但经过选择的5个高G系作测验种，能准确鉴定被测系中高、中G系的一般配合力，从而使其在选择高产杂交种的同时，又可选择新的骨干系和搭配亲本。本文还提出了选择的方法和标准。

| Abstract: | According to the standard of the evaluating results by the method of the diallel crossing,it is studied that the combining abilities of the leading maize self-bred lines behave in the test crossig for two groups of the parents which are 15 and 20 corn inbred lines respectively. The results showed that the evaluating results of the test crossing of leading lines are not accurate so that those can not be used to evaluate the combining abilities of inbred lines,But it is possible to select the high yield hybrids,the new leading lines and the collocation parents simultaneously by selecting five high GCA lines.The paper presents a methodolOgy and standard for selection. |
