In this study, a new cultivar of Lentinula edodes was bred from dikaryotic KFRI 490 and monokaryotic KFRI 536 by Di-mon method. The new breed was named “Poongnyunko” and physiological characteristics was investigated. Its optimal growing temperature was 25 oC, and it had thin density. Its colony was colorless and did not form any epithelium. On the 7 th day of mycelial growth, “Poongnyunko” was 56.6 mm, and showed higher cellulase activity compared with “Sanlim 4-ho”(52.9 mm). On the 5 th day of mycelial growth, “Poongnyunko” was 58.0 mm, and showed higher laccase activity compared with “Sanlim 4-ho” (55.6 mm). Its pH at a substrate was 6.0. Before cultivation, the pH of sawdust substrate was 4.7-5.5 went down to 3.7-3.9 after 120-day cultivation. After 60 days of cultivation, the change of CO2 was the greatest. During the cultivation, CO2 concentration in a growing bag was 4.67% to 3.90%.
