摘要
分析以自交系铁7922为主线的改良进程,明确铁7922改良系与黄系、旅系、黄旅合成系测配组合的优、缺点。以铁7922改良系为基础,添加外来相对应种质进行母本改良,以黄、旅合成系与Lancaster进行父本改良,利用单倍体技术选育区域强势品种。
The improved process, which main line was inbred lines of Tie7922, was introduced. And the study clear the advantages and shortcomings of Tie7922 that in combination with Huang line, Lv line and Huanglv line. Base on Tie7922 improved lines, the female parent improved with external corresponding germplasm and paternal improved between Huanglv line and Lancaster were conducted. So, using the technology of haploid and breeding strong regional varieties were the premise and foundation.
