高贵化回交育种技术在凉蔗2号遗传亲系中的应用探讨

Discussion on the Noble Back to hand Breeding Technology In Cool Sugarcane-2 in Genetic System

凉蔗2号亲系广泛应用高贵化杂交育种方法,引入异质血缘多次回交,打破连锁遗传,重组有利基因,促进血缘多样化,实现超亲。进行凉蔗2号亲系遗传高贵化杂交技术研究,有利于为凉蔗2号用作广亲和力亲本,实施远缘杂交制种工作提供有益借鉴。

Cool Sugarcane -2 is widely used in the noble to cross breeding methods, introducing time after time back into the blood heterogeneity, breaking chain genetic heredity, Restructuring favorable genes, Promoting blood diversification so as to realize super genetic system. With the application of the technology research, it can Widely used for parents to affinity, implement distant hybridization between provide reference to seed.
