前言 自交作物杂交后代处理的方法程序,同杂交育种的效果,工作效率,以及育种工作费用与用工量等方面关系极大。随着作物育种工作的不断提高与发展,以及对作物遗传、生理生态等方面知识的逐渐充实,杂交后代处理的方法,也不断地改进提高,使杂交育种工作更具有预见性与可靠性,从而可以用较短的年限较少的投资育成更好的有突破性的品种。目前,已有大批的研究报告(见附后的参考文献),对于不同的方法程 Preface The methods and procedures for the treatment of offspring of self-cross crop hybridization have a great relationship with the effects of crossbreeding, work efficiency, breeding cost and labor cost. With the continuous improvement and development of crop breeding, as well as the gradual enrichment of crop genetic, physiological and ecological aspects of knowledge, hybrid offspring processing methods, but also continue to improve and improve, making hybrid breeding more predictable and reliable, and thus Better breakthrough varieties can be bred with shorter years of investment. At present, there are a large number of studies (see attached references), for different methods
