在研究小麦不育系时,经常需要转育和繁殖少量不育系。通常是用镊子单穗授粉,或是将不育系和保持系共同套在一个套内任其自由授粉,或是设置小型障碍物隔离授粉。这些方法各有利弊。我们在回交转育和繁殖少量不育系时,在上述几种方法的基础上,综合杂交高粱的采粉、授粉方法,逐步摸索出了一种新的回交授粉方法。 In the study of wheat CMS, it is often necessary to transfer and propagate a few CMS lines. It is common practice to pollinate single spikes with tweezers, or to co-culture sterile and maintainer lines in a single kit for free pollination or isolate small pollination pollination. Each of these methods has its advantages and disadvantages. In the backcross breeding and propagation of a small number of sterile lines, based on the above methods, the comprehensive hybrid sorghum harvesting, pollination methods, and gradually developed a new method of backcross pollination.
