在2011年2月19-20日的三亚玉米育种论坛上,郑单958的发明人堵纯信先生重点讲了雄性不育制种的问题。这是一个很重要的发言,理应引起我国玉米育种界的普遍关注。最近几年,甘肃制种农户提出母本不去雄的要求,企业不得不另外雇人到田间去雄。这样一来,进一步增加了制种成本,同时质量也难以保障。一项看似不合理的要求,却迫使我们不得不把引进和推广去雄机械提上日程。但中国玉米育种受紧凑型的影响很深,不适合用机械去雄。这将迫使中国玉米育种者改变植株形态,像美国品种那样,采用上部叶
At the Sanyu Maize Breeding Forum on February 19-20, 2011, Mr. Jung Chun-sin, inventor of Zhengdan 958, focused on the question of male-sterile seed production. This is a very important statement that should arouse the general concern of the corn breeding community in our country. In recent years, farmers in Gansu Province have raised the demand that their mothers will not increase their jobs. Enterprises have to hire other people to work in the fields. As a result, the cost of seed production is further increased, while the quality is hard to guarantee. A seemingly unreasonable request forced us to introduce and promote the removal of machinery to the agenda. However, China’s maize breeding by the compact type of deep impact, not suitable for mechanical removal male. This will force Chinese breeders to change their plant morphology, as the U.S. variety does, using upper leaves
