摘　　要：开创性地提出了类回交育种方法,即利用性状优异的单交后(高)代与该单交组合的子一代杂交,产生的杂交群体作为起始群体开展选育种;分析了类回交育种的意义和重要性,类回交是比单交、复交、回交更有效的杂交方式,能快速、高效地育成品种。应用类回交育种方法,开展了常规稻品种的选育,目前已初见成效。The approach of backcross-like breeding was put forward creatively,hybrid population derived from F1/Fn of one single-cross was chosen as beginning population to develop new variety. The importance of backcross-like breeding was analyzed,it was more efficient than such cross patterns as single cross,multiple cross and back cross,and it could develop new variety efficiently and quickly. Through applying the method,inbred rice variety was developed and some achievement was made.
