摘　　要：金稻优122是广东省农业科学院水稻研究所用自育不育系金稻13A与自选的抗稻瘟病恢复系广恢122配组育成的弱感光型三系杂交稻新组合,2008年1月通过广东省品种审定。该组合高产稳产,2005和2006年晚造参加广东省区试,分别比对照博优122增产8.59%和5.95%,均达显著水平,适宜广东、广西作晚稻种植。Jindaoyou 122 is a new three-line hybrid rice combination with weak photosensitivity derived from Jindao 13A and Guanghui 122 with blast resistance, both of which are developed by the Rice Research Institute of Guangdong Academy of Agricultural Sciences. It shows high and stable yielding abilify. In the late cropping regional trials of Guangdong Province in 2005 and 2006, its yields were significantly higher than those of the check hybrid （ Boyou 122） by 8.59% and 5.95%, respectively. It is suitable for growing as late rice in the provinces of Guangdong and Guangxi. In January, 2008, Jindaoyou 122 was certified for release by Guangdong Provincial Crop Variety Appraisal Committee.
