诱发染色体易位培育小麦抗病品种早有报道,并应用于生产。水稻方面,日本已诱变一批粳稻易位系用于基因定位,但未用于生产。而籼稻易位系研究未见报道。本研究是在籼稻育种方面利用染色体易位以打破有利基因与不利基因的连锁,建立新的有利基因的连锁,育成早稻中熟、高产新品种“青威1号”和“青威2号”,其易位选育过程如下。 1980年早造以高产、中熟,但高感稻瘟病的品种“青二矮”作母本,以“V_(20)”ד圭630” Induction of chromosome translocation Wheat resistant varieties have long been reported and applied to the production. In rice, Japan has mutated a number of japonica translocations for gene mapping but has not been used for production. Indica rice translocation lines have not been reported. In this study, the use of chromosomal translocation in indica rice breeding to break the chain of favorable genes and unfavorable genes, the establishment of new favorable gene linkage, breeding early maturing rice, high yield new varieties “Green Granville 1” and “Green Granville 2” The translocation breeding process is as follows. Early 1980 to create a high yield, medium, but highly susceptible to the rice blast “Qing Er short” as the female parent to “V_ (20)” × “Kyu 630”
