卫星搭载水稻材料万2B、万3B的变异研究
Variations in satellite piggyback rice seed materials, caused under the space environment
摘要
Abstract
[Objective]The present research work were conducted by using rice seed material obtained from the recoverable satellite piggybank service in order to explore the variations and to select the mutant lines for breeding new high performing rice varieties. [Method]The dry seeds of rice maintainer line materials Wan 2B and Wan 3B, provided by Three Gorges Academy of Agricultural Sciences, Chongqing, were planted in field after carrying back from recoverable space satellite “Shenzhou VI”. The original seeds were used as the control to investigate the genotypic and phenotypie variations caused by the high vacuum, microgravity and strong radiation conditions of the space. [Result]The significant variations in seeds, obtained from recoverable satellite, were observed mainly in SP2 generation, and most of the aronomic traits showed their least and highest variations in different seeds, while showed stable in SP3 and SP4 generation. [Conclusion]There is a great potential of getting mutant variants in SP2 generation in seeds obtained from the recoverable satellite. The selection of the mutant lines having desirable characteristics and their use in breeding high performance rice varieties through space breeding program seems to be an interesting futuristic research.关键词
