摘要
用特种稻南丰糯种子搭载神舟4号宇宙飞船,进行空间诱变处理,诱变后代材料经多代选择,育成特种稻新品种航香糯,2009年1月通过广东省农作物品种审定。与原品种南丰糯相比,航香糯的稻瘟病抗性提高,粒型变细长,有效穗和实粒数增加,且具有香味。本文还就空间诱变育种的应用效果和变异材料稳定的世代进行了讨论。
A new special rice variety Hangxiangnuo was bred by several generation selections of the progeny of the rice variety Nanfengnuo which was carried by the spacecraft Shen zhou No 4.Hangxiangnuo was permitted to release by the Crop Examination and Approval Committee of Guangdong Province in January,2009.Compared with its parent variety Nanfengnuo,Hangxiangnuo has better resistance to blast,greater length-width ratio of grain,more panicles per plant,filled grains per panicle and fragrance.The efficiency of space mutation breeding and the generation at which mutant traits become homozygous were also discussed in the paper.
