摘　　要：辐269是以早籼品系中07-108为母本、早籼品系04YK17为父本去雄杂交,F_(1)代干种子经过80 Gyγ-射线辐照处理后,采用系谱法选育出的两系早籼恢复系。该恢复系具有配合力强、花粉量大、制种产量高、谷圆粒、直链淀粉含量较高和高抗稻瘟病等特点。配组的两系杂交早稻陵两优69(组合名称湘陵628S×辐269)于2018年通过江西省农作物品种审定委员会审定,并于2019年通过湖南省引种备案。Fu 269,a two-line early indica rice restorer line,was developed through the pedigree breeding method by irradiating F_(1) dry seeds of Zhong 07-108×04YK17 using 80 Gy γ-rays.It has the primary characteristics of strong restoring ability,heavy pollen load,high hybrid seed yield,round grain,high amylase content,high resistance to rice blast,et al.The two-line early indica hybrid rice combination Lingliangyou 69(the combination of Xiangling 628S×Fu 269)was approved by the Jiangxi Provincial Crop Variety Approval Committee in 2018 and registered for introduction in Hunan Province in 2019.
