| 摘 要： | 利用高空气球、返回式卫星和飞船搭载水稻干种子进行空间诱变处理 ,开展空间诱变效应及其育种应用研究。在诱变后代选育出航育 1号、R2 0 36和航香 1 0号等新品种 (系 )。对空间诱发的多蘖矮和大粒突变体进行了形态学鉴定和遗传学研究。空间诱变效应表现为处理当代生理损伤轻 ,植株结实正常 ,后代突变频率因不同基因型和性状差异较大。空间环境诱变敏感性与60 Coγ射线辐照敏感性相关不显著。

| Abstract: | Dry seeds of rice varieties were carried by high altitute balloon, recoverable satellite and space craft for space mutation and its biological effects were analyzed compared with 60 Co γ\|radiation. The new varieties Hangyu No.1, R2036 and Hangxiang No.10 were developed. Some mutants including large grain and tiller dwarf were identified and bred. Space mutation has its characteristics with small radiation damage and normal seed setting rate and relative higher mutation frequency for some traits compared with 60 Co γ\|radiation. Mutation frequency of space mutation greatly varies according to different genotypes and traits. Radiation sensitivity of space environment has no significant correlation with that of 60 Co γ-radiation. |
