Abstract
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 $25^{\circ}C$, 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 $CO_2$ was the greatest. During the cultivation, $CO_2$ concentration in a growing bag was 4.67% to 3.90%.
