Breeding and Application of New High-yielding and Weakly Photosensitive Hybrid Rice Combination Jindaoyou 122

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 ability. 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.
