Oak mushroom is one of the most important non-timber forest products at the forest sector in Korea. In recent years, the Korean farmers have suffered from the import increase of saw bed medium from Chinese and the price decrease of the oak mushroom. In order to overcome this phase, it is important to develop good varieties that can compete with Chinese varieties. National Institute of Forest Science is studying to develop excellent varieties through the Golded Seed Project. We report some of the results as part of that. The strains of oak mushroom were made through mono-mono cross method using domestic distribution varieties. Sawdust cultivation was carried out on 100 - day cultivation and 3 - stage mushroom yield using 2 kg hexahedron culture medium. Of these, 60 strains were used for sawdust cultivation, and 3431 strain (23%) was selected when the yield was 20% or more of the weight of the medium. Four strains (3396, 3414, 3419, 3430) were selected when the mushroom yield was 15% to 20% of the weight of the medium. 3404 strain with excellent mushroom shape was selected, though the yield was low (10%). Generally, mushroom yield was the highest in the first stage, and the number of mushrooms in the second stage was decreased rapidly. Also, 10 strains did not produce mushroom in this study. The 3431 strain occurred mushroom production with 87% yields in the first stage and did not occur in the third stage. The 3404 strain with excellent mushroom shape occurred in primary and tertiary. The average weight of mushrooms was 13 g and 54g, respectively. The strains (3431, 3404) will be used for the selection of varieties through cultivation test in the future.
