摘　　要：特优７０ 是三明市农科所用龙特普 Ａ 与明恢７０ 配制的籼型杂交中、晚稻组合，具有高产、抗病、米质优良、制种产量高的特点。参加全国、福建省、三明市三级区域试验，产量显著比对照增产。１９９９ 年３ 月通过了福建省品种审定委员会审定，被福建省、三明市列为重点示范推广新组合，并已在江西、湖南、广西、广东等省进行大面积的示范推广。本文介绍了该组合的主要特征特性、产量水平，并对产量构成因素进行统计分析。Teyou 70 (Te A/Minghui 70), developed by the Agricultural Science Research Institute of Sanming, was a mid-late indica hybrid rice. It has the characteristics of high yield, resistance to blast, good grain quality and high seed yield. The average yield increases by 7.86% compared with the check in regional, provincial and national yield trials. It was examined and approved for release in Fujian Province in 1999. It was selected as an important item for extension in Sanming City and Fujian Province and has been extended to large area in Jiangxi, Hunan, Guangxi, Guangdong provinces, etc. The major character, yield and yield formation analysis of Teyou 70 are introduced in this paper.
