在进行水稻远缘杂交时,除掌握花期相遇而外,还必须解决一个花时相遇的难题。过去通常采用的“温汤去雄”、“剪颖去雄”和“套袋去雄”等方法,因必须在一定的时间、适当的温度和在晴暖天气下进行,由于这些条件的限制,远不能适应当前的杂交工作。为此,我们在进行水稻远缘杂交的同时,摸索出一种能在水稻抽穗期间的任何时刻、任何天气条件下均能进行去雄的方法——“剪—温去雄法”,经反复试验效果良好。 In the distant hybridization of rice, in addition to meeting the flowering encounter, but also must solve a difficult problem encountered. In the past, methods such as “warm soup to remove cocks”, “clipping to sterilize” and “bagging to remove cocks” were generally adopted in the past because of the necessity of being carried out at a certain time, at an appropriate temperature and in a fine and warm weather. Due to these restrictions, Far from being able to adapt to the current hybridization work. For this reason, while exploring the distant hybridization of rice, we found out a method that can be emasculated at any moment during rice heading and any weather condition Test results are good.
