摘　　要：针对广东省早造杂交水稻生产上主要利用籼稻不育系珍汕97A和优ⅠA等育成的杂交稻组合普遍存在的米质差和稻瘟病抗性差等问题,连山壮族瑶族自治县农业科学研究所于2003年以引自佛山农科所的优质稻种质粳籼89与由省农科院水稻研究所育成的三系保持系种质五丰B杂交,进而选育三系新保持系和新不育系的育种改良工作,于2009年早造育成了早籼稻新不育系吉田A。阐述了早籼稻新不育系吉田A的选育经过、特征特性、配合力表现,总结了其繁殖技术,以供参考。The rices hybridized by Zhenshan 97A and You I A had the character of poor quality and bad blast resistance. Lianshan Zhuang and Yao Autonomous County agricultural science research institute developed early indica rice three-line sterile lines Jitian A. This paper described its selective breeding process, characteristics, combining ability and performance, as well as the reproductive technology, in order to provide reference.
