| Abstract: | The dry seed of mid maturing Japonica rice Yanjing 10 was used for space mutation breeding which was carried by a satellite for 15days in 2006 Through three generations of breeding, a group of mutants were obtained. In the article, we reported in detail the breeding procedures, proposed the breeding technical method for space mutation for rice improvement. Planting multiple seedlings per hill to prohibit tillering at SP1 generation, and bulked selection in combination with directional selection at the sp2～sp3 generation were the two keypoints of the breeding methods. |
