摘　　要：广优明118(广抗13A/明恢118)是福建省三明市农业科学研究所育成的高产三系杂交稻新组合。在福建省晚稻区试中,比对照汕优63增产8.87%,抗稻瘟病,稳产性好,米质优于对照汕优63。该组合日产量高,单位面积有效穗和穗粒数协同增长,有效穗增加对产量提高的作用更大。Guangyouming 118 is a new three-line hybrid rice combination bred by Sanming institute of agricultural sciences,Fujian.Regional trials deplayed that the yield of Guangyouming 118 was 8.87% more than the control（Shanyou 63）,its resistance to blast disease,yield stability,rice grain quality were superior to those of the control（Shanyou 63）.The new combination had high daily output,coordinated increase of effective panicles per unit area with grain number per panicle.Effective panicles contributed more to yield increase.
