摘　　要：为确定航天品种功能稻米——粤航一号抗性淀粉含量,给临床观察膳食干预后果判断提供实验参考数据,并了解航天育种对该品种大米抗性淀粉含量的影响,用Goni测定方法测定了粤航一号、富硒粤航一号、长丝占、粳籼89 4种稻米的抗性淀粉含量。结果表明,粤航一号、富硒粤航一号、长丝占、粳籼89 4种稻米的抗性淀粉含量分别是(0.30±0.11)%、(0.47±0.37)%、(0.31±0.66)%、(0.36±0.62)%。可见粤航一号与亲本长丝占,及与富硒品种富硒粤航一号,和非航天品种优质大米粳籼89在抗性淀粉含量上无差异,航天育种对该品种稻米抗性淀粉生成遗传特征无影响。To determine the content of resistant starch （RS） in this space functional rice Yue - Hang 1 , so as to supply experimental data for clinical diet intervention and understand the influence of space breeding to RS contain in this kind of rice, Applying Goni method the content of RS in Yue - Hang 1 rice, selenium - rich Yue - Hang 1 rice, Chang - Si - Zhan rice, Jing - Xian 89 rice was determined. The results showed that the content of RS in Yue - Hang 1 rice, rich - selenium Yue - Hang 1 , Chang - Si - Zhan rice, Jing - Xian 89 rice was respectively （0.30 ± 0.11 ） %. （47 ± 0. 37） % , （0. 31± 0.66）%, （0.36 ±0. 62）%. Concludes the content of RS in Yue - Hang 1 rice are no difference with rich - selenium Yue - Hang 1 rice, Jing - Xian 89 rice and its parents Chang - Si Zhan rice. Space breeding has no effect in genetic characteristic in contains of RS in this kind.
