玉米品种配合力测定工作,是品种资源研究的重要组成部分。我所在五十年代初,结合品种间杂交育种工作,曾先后测定过一些早熟品种的配合力。在测定中,配合力表现突出的一些品种,如华农二号、敏玉米、大红袍、小金子、勤棒子、红轴、青县红垂黄、东檀山、宁晋二耧、MV_1、加拿大969等,曾做为杂交亲本在试验和生产中广泛利用,对当时的育种工作曾起到一定推动作用。五十年代末至七十年代中,品种配合力测定工作基本停顿。自1978年玉米品种资源被列为研究任务后,我们开始有计划地开展此项工作,现将初步结果简结于后。 Determination of maize varieties with the ability to work, is an important part of the variety of resources. In my early fifties, with the crossbreeding and breeding of varieties, we determined the combining ability of some early-maturing varieties successively. In the test, some varieties with prominent combining ability such as Hua Nong 2, Min Ma, Dahongpao, Xiaogongzi, Qinhuangzi, Hongxian, Qingxianghuohuang, Dongliangshan, Ningjin Erpi, MV_1, Canada 969 Etc., used to be the parent of hybridization widely used in experiment and production, and played a certain role in promoting the breeding work at that time. From the late fifties to the seventies, the determination of variety combining ability basically stopped. Since the maize variety resources were listed as a research mission in 1978, we started to carry out this work in a planned manner and we now summarize the preliminary results.
