芝麻不同品种对空间诱变的敏感性及生物效应研究初报

Preliminary studies on biological induction effects of space treatment on sesame varieties

５个纯合芝麻种质材料搭载我国发射的第１７颗返地式卫星空间处理１５ｄ后，Ｍ０种子外部性状与未处理对照间无明显变化，Ｍ１表现出叶形、育性等外部形态性状变异，品种间敏感性不同。

Fifteen days space treatment of five pure sesame varieties seeds were conducted by taking the 17th earthreturning satellite. No differences were found between treated seeds and contrast in M0. Nowever, leaf shape, fertility and seed colour variants were discovered in M1 generation. And scissor shape leaf was first reported so far. Five varieties showed different induction sensitivities.
