Artificial culture Cordyceps militaris is the well way to solve the insufficient resource of wild Cordyceps.In the process of artificial culture Cordyceps militaris,the degeneration phenomenon of the strains is the restrictive bottleneck of the industrial exploitation.Isolation and purification of Cordyceps militaris strains and continuous passage,the identical strain was cultured in two methods:sporocarp and mycelium culture.Based on the test index of growth potential and yield,the yield and test genetic stability of the identical strain under different culture methods were studied,in order to screen a culture method without the effect of strains generation.The results showed that after six generations,the strains grew well and inherited stably in mycelium culture,although they obviously degenerated in sporocarp culture.Mycelium culture has a good prospect in industrial production.
