Title: Observation and Analysis on Plant Height of SP_3 of Wheat Dwarf Mutant Lines by Space Mutation
Abstract: Six dwarf wheat mutant lines were derived from SP2 of wheat variety Han 6172 which was boarded on the space breeding satellite Shijian No.8,and the plant height of SP3 was observed.The results showed that the mutated dwarfing trait performed well in SP3.The plant height of six mutant lines was ranged from 51.25 cm to 61.54 cm,which reduced 5.43-15.72 cm,and reduced by 8.11%-23.47% than original parents.There was a very significant difference in plant height between mutant lines and original parents.The proportion of stable mutated dwarf line was low(16.67%),only 6172 SP Ai 3 performed uniform,while the plant height of other mutant lines was segregating.The observation of field characters should be paid attention to.According to the character expression of different mutation groups,the breeding methods of population harvesting and single plant harvesting should be used.
