Abstract

Mutagenic effect on the mutant highproducing strain ZJAVY1203 and the original strain ZJAVA1 irradiated by ion beam of ¹²C⁶⁺ have been investigated. The experimental results indicated that the original strain has higher survival rate and stronger resistance to radiation than mutant highproducing Strain at dose of 10 Gy. The mutant highproducing strain has higher survival rate and stronger resistance to radiation than the original strain at the dose higher than 30 Gy. The lethality was 97% and the highest rate of orthomutation was 34.2%， when ZJAV A1 was irradiated by 50 Gy ¹²C⁶⁺ beam. The lethality was 94.97% and the highest rate of orthomutation was 23.5% when ZJAVY1203 was irradiated by 30 Gy ¹²C⁶⁺beam. The best radiation dose is decreased by progressivity irradiation.
