These experiment was conducted to find the superior strain selection, cultivation technique and optimum environmental condition of NAMEKO mushroom culture using plastic container. The results was following as: Mycelium of Pholiota nameko grown well at MCM and Hamada media, and its media acidity was pH 5~6. The optimum temperature condition for growing mycelium was 25℃. Under 15℃ and above 30℃ of temperature condition, mycelium growing speed was delayed remarkably. Among the 29 strains of NAMEKO mushroom, the most productive strains was JNM19007, JNM19026, JNM19027 and JNM19028. The optimum media composition rate for produce fruitbody was pine sawdust 80%+wheat bran 20%. In this condition, the average fruitbody amountwas 188g per 1,100cc container. The optimum post-culturing period was 50 days and mushroom sprout appeared 7 days after old mycelia removed. The suitable temperature was 12℃ for induce sprout, growing period was 16℃ and the optimum relative humidity was 95% in all culturing periods.
