Screening of dominant strain in Ganoderma lingzhi cultivated in Jiaoling area

To screen the suitable strain of Ganoderma lingzhi cultivated with bagging，six strains were employed for cultivation test. The suitable strain was selected base on the comprehensive analysis of growth situation， characteristics，yield，product quality and value. The results showed that the strain G. meiling NO.3 grew well and fast（ 0.83 cm/d），produced the highest spore powder，yield reaching a mean of 13.17g/bag，38.24% higher than CK，and the spore yield was 41.39% higher than fruitbody. The spore crude polysaccharides content was 0.59%， selenium content was 0.0832 mg/kg，and 15.69% and 43.68% higher than CK respectively. The output and income were 28.58% and 29.21% higher than CK produced by one ton raw material. In conclusion，G. meiling NO.3 produces better yield，good quality and well benefit，is suitable to popularize in spore collection cultivated area using bagging cultivation technology.
