摘  要:
以中粳稻品种盐粳10号干种子为材料,于2006年经育种专用卫星搭载15d后返地种植。通过连续3代选育,从其后代群体中获得一批突变体。本文详细报道了选育过程,并提出了SP1代多本栽插、控制分蘖,SP2~SP3代混合选择和定向筛选相结合的水稻选育方法。

摘  要:
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.
