Abstract: In our previous paper it has been described that the space flight of maize seeds has significant influence on its photosynthetic pigment contents and young leaf ultrastructure (Zea mays L.).This paper deals with the different mutant types of space induced variation and their distribution in maize. Mutants obtained from Sp2(second generation by space treatment) to Sp3 show that amplitude of variability for space induced variations is large enough. Five type mutants for space induced variation are obtained,they are:1)Special high plant and dwarf plant mutants,resistance to B.maydis and E.turcicum all;2)Leaf-blade mutant;3)ear length mutant;4)multi-ear mutant;5)kernel type mutant.Eleven mutants are obtained,i.e.Mut1,Mut2,Mut3,Mut4,Mut5,Mut6,Mut7,Mut8,Mut9,Mut10,Mut11 etc.Mutant element probrem are discussed.
