Abstract:
A laboratory preserved strain of C.militaris(‘BY2’) was used to be treated by 60Co-γ ray combined with ARTP mutagenesis，After primary screening，rescreening and stability tests，the colony characteristics and fruiting body yield of the mutant strains were studied to obtain high-yield strains of C.militaris.The results showed that three high yield mutants were screened out.Compared with the original strain，the fruit body yield of the high yield mutants was increased by 32.27%,36.00%and 33.87%，respectively.The genetic stability experiment and factory production showed that the mutant strain BY2-1122 was the most stable strain and its fruiting body yield was significantly higher than that of current producing strain，with an increase of 17.3%.Our study showed that the breeding of C.militaris treated by 60Co-γ ray combined with ARTP could obtain the high yield fruiting body strain.
