Abstract: The production performance(i.e.,mycelium growth,growth period,yield and biological quality) of 8 strains of Agaricus blazei Murrill commonly found in Fujian was evaluated.The results showed that the local and No.11 strains were most desirable with stable yields.The No.11 strain had the highest yield among all.It had a 66d growth period,robust mycelium development,and thick,strong,dense,light-colored,rapid growth of fruiting body formation.In contrast,the local strain had a 55d growth period and was slightly less desirable on other characteristics than the No.11 strain.Nonetheless,they both were considered suitable for mass cultivation in Fujian.
