摘　　要：广8A是广东省农业科学院水稻研究所育成的增城丝苗型优质不育系,具有广东丝苗型稻米品质、稻瘟病和白叶枯病抗性好、配合力强和综合农艺性状优等特性。截止到2021年,以广8A为母本组配的系列杂交组合已有39个通过国家级或省级品种审定,尤其是广8优165、广8优169、广8优2168和广8优金占均较好地达到了品质、产量、抗病的协调统一;同时,这4个品种在生育期上互补性强,满足了广东省各个稻作区对早、晚稻的种植需求。它们的推广应用,优化了广东省杂交水稻品种结构,为广东省杂交水稻的优质化更新换代作出了较大贡献。2013年以来,这4个广8优系列优质杂交稻品种多次被列为广东省农业主导品种和区试对照品种。2019年,“丝苗型优质杂交稻广8优系列组合推广应用”荣获广东省农业技术推广奖一等奖。Guang 8A is a high-quality male sterile line of Zengcheng Simiao type developed by the Rice Research Institute of Guangdong Academy of Agricultural Sciences. It has the characteristics of Guangdong Simiao-type rice quality, good resistance to rice blast and bacterial blight, strong combining ability and excellent comprehensive agronomic traits. Up to 2021, there had been 39 hybrid combinations derived from Guang 8A registered and released to commercial production at the national or provincial level. Among them, Guang 8 You 165, Guang 8 You 169,Guang 8 You 2168 and Guang 8 You Jinzhan achieved the target of integration of quality, yield and disease resistance.Meanwhile, these four varieties are highly complementary in the growth period, which can meet the planting needs of early and late rice in each rice growing area of Guangdong Province. Their popularization and application optimized the structure of hybrid rice varieties and made a great contribution to the upgrading of high-quality hybrid rice in Guangdong Province. Since 2013, these four high-quality hybrid rice varieties of Guang 8 You series have been listed as the leading agricultural varieties and as the control varieties of regional trials in Guangdong Province for many times. In 2019, "The promotion and application of Simiao-type high-quality hybrid rice varieties of Guang 8 You series" won the first prize of Guangdong Agricultural Technology Promotion Award.
