目前进行小麦杂交,主要采用剪颖杂交法。在操作过程中,要经过整穗、剪颖、去雄等工作,称之为整穗剪颖杂交法。这种方法,在天晴无雨时,授粉效果好,一旦遇上多雨季节,由于去雄后的麦穗不能及时授粉,杂种结实率降低。近几年,我们采用全穗剪颖杂交法,在多雨季节进行小麦杂交取得较好的效果。全穗剪颖杂交法,就是在
The current hybridization of wheat, mainly using shear-method hybridization. In the process of operation, to go through the whole spike, shearing Ying, to male and other work, called the entire ear shear-resistant hybrid method. This method, when the weather is sunny, pollination effect is good, in the event of a rainy season, because after the emasculation of the wheat can not be timely pollination, seed setting rate decreased. In recent years, we have used the whole-cropping shear-bar hybridization method to achieve better results in the hybridization of wheat in the rainy seasons. Whole scissors shear hybrid method, is in
