Abstract
Flammulina velutipes is the representative edible mushroom in Korea. It makes up around 18% of the total mushroom production and accounts for about 36% of the total mushroom export. Despite being one of the most industrially important mushroom in Korea, the distribution rate of domestic cultivar was low (~31.6%) in 2020. Therefore, we need a new domestic cultivar with high quality as the main export mushroom. We developed a new white domestic cultivar, 'Seolhan', bred by mating two monokaryotic strains isolated from Baekseung and Woori-1ho. The optimum mycelial growth temperature was 25℃ and Seolhan had higher mycelial growth than the control at 20 and 25℃. In bottle cultivation, the optimum temperature of incubation was from 15℃ to 17℃ and the growth temperature of Seolhan was 7-8℃, which was slightly higher than that of the control. The yield of Seolan was 226.5±8.0 g, an increase of 18.4% compared to the control. The period of primodia formation also was a couple of days ahead. In morphological traits, the pileus of Seolhan was smaller than that of the control, the stipe was thicker, and the color brighter. As the results of replacement culture and genetic diversity test, it was confirmed that Seolhan was genetically different from other white varieties.
