六十年代日本新城长友以籼稻“钦苏拉包罗Ⅱ”为母本,以“台中65”为轮回亲本,通过杂交、回交,选育出包台型不育系、保持系及相应恢复系,实现粳型三系配套,为利用杂种优势提供了方法。但由于包台型三系遗传背景类同,杂种一代优势不显著,不能用于生产。七十年代以来,国内粳型三系进行了广泛测恢,结果证明粳稻恢复系资源 In the 1960s, Changyou, Japan’s new town, took indica rice “Qin Su La Bao Luo Ⅱ” as its female parent and “Taichung 65” as its reincarnated parents. Through crossbreeding and backcrossing, the long- Department, to achieve japonica three lines supporting, to provide a method for the use of heterosis. However, due to the inclusion of Taiwan-type three-line genetic background similarities, hybrid generation advantage is not significant, can not be used for production. Since the seventies, the domestic japonica three lines have been widely measured, the results show that japonica restorer resources
