Cultural Characteristics of New Variety Lentinula edodes, Poongnyunko on Bed-log and Sawdust Substrate

In this study, a new strain of Lentinula edodes (Shiitake) Poongnyunko was bred from dikaryotic KFRI 490 and monokaryotic KFRI 536 by Di-mon crossing method. In this study, the productivity was conducted through bed-log and sawdust substrate cultivation. The Poongnyunko showed significant intensive production from summer to autumn. Optimum temperatures of fruit-body formation were . The total amount of fruit-body production during 4 years by bed-log cultivation was , and total yield of fruit-body until the 3rd flush was 648 g/ 2 kg. In case of sawdust substrate cultivation, the mycelial incubation period was 110~130 days. The suitable temperature and relative humidity were and respectively.
