采用籼稻恢复系与带粳稻亲缘的籼稻恢复系杂交低世代测鉴法选育而成的广谱性恢复系盐恢559,具有恢复力强、恢复谱广、品质优良、抗逆性好、花粉量大、制种产量高等特点。分别用野败型、矮败型、印水型质核互作不育系及光温敏核不育系与盐恢559进行配组,其组合均表现出很强的杂种优势和优良的综合性状。育成的杂交组合特优559、汕优559、协优559、Ⅱ优559、29优559、培两优559及丰优559先后通过江苏省、贵州省、安徽省、湖南省和国家品种审定,并相继在生产上大面积推广应用。
A broad-spectrum restorer line Yanhui 559, which was bred from indica restorer lines of indica restorer line and indica restorer line with japonica compatibility, was characterized by its strong recovery, broad spectrum of recovery, good quality, good resistance to stress, Large amount of seed production and higher characteristics. Respectively wild-type, dwarf-defeated type, water-printing type of nuclear-mediated sterility and photo-thermo-sensitive genic male sterile line and salt Hui 559 for the group, the combination showed a strong heterosis and excellent synthesis Traits. The hybrid combinations Teyou 559, Shanyou 559, Xieyou 559, Ⅱ You 559, 29 You 559, Peiliangyou 559 and Fengyou 559 passed the examination and approval of Jiangsu, Guizhou, Anhui, And one after another in the production of large-scale promotion and application.
