本文分析了Lan杂优群Mo17亚群选系及其衍生系自20 世纪70年代至今,在中国玉米育种和生产中的研究与应用。 结果表明:优良玉米自交系Mo17、C103、77、444等和玉米杂交 种中单2号、丹玉13、烟单14、七三单交、四单19等对中国玉米 育种研究和生产应用产生了重大影响,也做出了很大贡献。其 间利用的主要杂优模式为Mo17亚群与自330亚群、塘四平头 杂优群和旅大红骨杂优群。新世纪如何继续沿用原有杂优模 式和创建新的杂优模式都值得玉米育种家高度重视,为中国玉 米育种和再上新台阶奠定基础。
In this paper, the research and application of Lanzhou excellent group Mo17 subgroups and their derived lines from the 1970s to the present in maize breeding and production in China were analyzed. The results showed that the maize inbred lines Mo17, C103, 77, 4444 and other maize hybrid maize Zhongdan 2, Dan Yu 13, Yidan 14, Has had a significant impact, but also made a significant contribution. The dominant heterotic patterns utilized during this period were the Mo17 subpopulation and the 330 subpopulations, the Tongsiping head megalopolis and the Luda red bone hybrid group. How to continue using the original heterosis pattern and create a new heterotic pattern in the new century deserves the attention of corn breeders and lay a foundation for China’s maize breeding and re-entering a new stage.
