摘要
太空环境条件特殊,可以使植物细胞发生突变,从而产生新物种。与常规育种方法相比较,此育种方法具有变异幅度大、稳定快、周期短等优点,不仅植株明显增高增粗,产量和品质也大为提高,中国已经育成如"赣早籼47号"、"赣棉12号"和"太空莲子"等多种的优良太空品种。今后除了继续重视农作物的品种培育外,还应加强树种和花卉的太空育种,只有牢牢把握未来的太空育种方向,才能保持中国在这一领域的世界领先地位。
The special environment in space may bring out plant mutation, so new species come into being. Comparing with conventional breeding techniques, space breeding possesses many virtues such as wider variation, stabilization more quickly and shorter breeding periods etc., it not only make plant higher and stronger, but also improved the yield and quality. China has been bred many excellent space species like 'Ganzaoshan No. 47', 'Ganmian No. 12' and 'space lotus' etc. Aftertime scientist of space breeding should attach importance to tree and flower besides crop. Only holding the future space breeding direction, can china keeping one-up level in this domain.
