        Studies were made to find out the mycelial growth and rotting characteristics of 91 Lentinus edodes isolates collected or hybridized in Korea and abroad, and their adaptability to bag-culture. The results are as follows. 1. There were little differences in mycelial growth at PDA and oak (Quercus mongolica) sawdust-based medium, and rotting among high-, mid- and low temperature types of L. edodes isolates. But. the fruit yield of high-temperature type was much higher than those of the other two types. The fruit yields of the isolates in the same strain group were apparently different. 2. From the sawdust-based culture of 91 isolates, FRI 221, FRI 208 and FRI 169 were selected as excellent strains in yield and Quality, showing fruiting of 157g, 152g and 119g per 1㎏-medium, respectively. 3. Attempts to culture in various media with different substrates resulted in almost same fruit yields, and the yield was proportional to medium weights as 2.5㎏-medium showed 2.5 times more yield than 1㎏ -medium. Fruit yields were different according to incubation periods and the period of little more than 100days was best. 4. When the correlation analyses among mycelial growth, rotting ability, yield and fruit-shape normality were made with the 91 isolates, mycelial growth at sawdust-based medium showed highly positive correlation with that at PDA, while fruit yield was negatively correlated with mycelial growth in PDA and sawdust-based medium.
