杂交育种是创造新品种最有效的一种育种方法,其最大优点是能将亲本的优良特性特征汇集于子代内,通过定向培育和人工选择,选出人们需要的新品种来。我省近几年来选育出的小麦良种33个,有11个是通过杂交方法培育而成的,增产效果一般在10一50％。但是这种方法,比较费工费时,技术性也比较强,培育出一个品种,一般需要七、八年之久;如果亲本选配不当,育种目标不够明确,育种技术不能熟练掌握,就很难培育出理想的品种来。现根据工作体会,并参考省内外先进经验,在小麦杂交育种技术上,提出一些初步意见,与育种工作同志们共同商讨。 Hybrid breeding is the most effective breeding method for creating new breeds. Its greatest advantage is that it can bring together the excellent characteristics of parents in offspring and select the new breeds that people need through directional cultivation and manual selection. In recent years, 33 varieties of wheat have been bred in our province, and 11 have been cultivated through hybridization. The yield increase is generally 10 to 50%. However, this method is more labor-intensive and more technical. It takes seven or eight years to cultivate a variety. If the parent is not properly selected, the breeding goal is not clear enough and the breeding technology can not be mastered, it is very difficult to cultivate Out of the ideal variety. Now based on the work experience, and with reference to advanced experiences both inside and outside the province, we put forward some preliminary opinions on wheat hybrid breeding technology and discussed with the breeding work comrades.
