The nine parental strains of Lentinula edodes including cultivar “Sanbaeghyang” were selected to develop new cultivar of Lentinula edodes with good cultural characteristics and high productivity. A total of 44 strains were obtained by mono-mono hybridization. We investigated their cultural characteristics and fruiting body productivity using sawdust media cultivation method. For the cultivation, rectangular shape polypropylene bags filled with 2 kg sawdust media containing 80% of Querqus spp. sawdust and 20% of wheat bran were used. The average weight loss of sawdust media of 44 strains was 9.7% after 100 days of incubation. Nineteen strains (43%) showed above-average rates of weight loss. NIFoS 3515 had the highest weight loss rate (12.7%) among the hybrid strains, followed by NIFoS 3530 (12.4%) and NIFoS 3519 (12.3%). Overall, fruiting body production was low. After the second flush of fruiting body production, the average weight of mushrooms was 40.8 g per 2 kg sawdust medium, because fruit bodies were formed by 17 strains (38.6%) out of 44 strains. Ten strains (22.7%) showed above-average productivity. The highest productivity was shown by NIFoS 3533 (417 g), followed by NIFoS 3512 (237 g), and NIFoS 3516(211 g).
