摘　　要：对2005年广西杂交水稻组合区试和筛选试验进行分析,结果表明,参试组合类型、数量、来源及区试入选率不断提高和多样化,产量水平、稻米品质都有所提高,初次出现米质符合国标一等食用籼稻品种品质的早稻早熟组合且通过省级审定;在抗病性方面,大部分组合对白叶枯病抗性较强,而对稻瘟病抗性相对较弱,最后从育种角度提出广西杂交稻选育创新的思考,供同行参考。According to the analysis of the data of Guangxi hybrid rice regional and filter trial in 2005 ,the types,number,source of combination and the ratio of selection were steadily enhanced and diversified. The yield and grain quality was improved to some extents. And it the first time that the early-cropping and early maturing hybrid rice combination grain quality living up to first grade of state quality standards. A majority of combination had strong resistance to bacterial blight,but weak resistance to the blast. Some considerations of breeding were put forward.
