Oyster mushroom is one of the economically important crops, accounting for 35% of the total mushroom production in Korea. ‘Baekseon’ developed on this study is a new variety of Pleurotus ostreatus with white pileus and stipe. It was bred by mating with monokaryons isolated from white mutant oyster mushroom naturally generated from ‘Gonji-7ho’ and ‘Wonhyeong-1ho’ at Mushroom institute, GARES, Korea in 2018. The optimum temperature for the mycelial growth was 28～31℃ on PDA medium and that for the primordia formation and the growth of fruiting body of ‘Backseon’ was 22℃ and 20℃ on sawdust media. It took 30 days to finish spawn running, 4 days to finish primordia formation, 4 days to finish fruitbody growth in the bottle culture. In the characteristics of fruit body, fruit body showed a bundle shape, pilei were round type and white, stipe color was white. Stipe shape was slender and longer than the control(‘Miso’). The yield per bottle in productivity test was 185 g/1,100 ml which was increased by 45% compared to the control(‘Miso’). The yield in the farm test, A(Pyeongtaek) farm and B (Yeoju) farm showed 184 g / 1,100 ml and 178 g / 850 ml per bottle, respectively. As results of the physical properties of fruit body, springness, cohesive, gumminess and brittleness of stipe tissue were 80%, 57%, 720 g and 57 kg, respectively. The values of them are lower than those of control(‘Miso’). When the wrapped fruitbody with antifogging film was stored at 4 ℃ for 28 days and room temperature for 4 days, the shelf life was enough to be edible.
