玉米矮化育种研究进展及发展前景

Review on Research of Maize Breeding for Dwarfness and Its Development Prospect

回顾了我国矮化玉米育种的研究进展,概述了玉米矮秆性状的遗传传递规律,结合数年的育种实践,找到回交和复合杂交等选育优良矮生自交系的方法,发现单基因矮生系和多基因矮生系间组配是选育优良矮秆杂交种的一条有效途径。

This paper reviewed the research and development of maize breeding for dwarfness, and summarized the genetic transfer rule of maize lowstem trait. Combining the many years breeding practices, we found out the method of selecting excellent lowstem line such as backcross and complex cross. Meanwhile, we found the combination of single gene lowstem line and multiple gene low-stem line is a efficient way of selecting excellent low-stem maize hybrid.
