‘Gonji-5ho’ a new variety of oyster mushroom, fitting for the bag culture, was bred by mating between monokaryons isolated from ‘Chiak-3ho’ and ‘Suhan-1ho’ . In the major characteristics of fruit body, the pilei were thick and gray and the stipes were thick and long with softness. It was great in elasticity and cohesivness of tissue as compare to Suhan-1ho. Compared to other varieties, it is suitable to growing at higher temperature. The range of optimum temperature for the mycelial growth was around 26～29℃ and that for the pinheading and growth of fruitbody was around 18～20℃. But when grown in less than 15 degree, it was become non-uniform growth, longer culture period, and uneven stipes. In the bag culture, it was required around 18 days in incubation period and 3 days in primordia formation. The fruit body was grew vital and uniform. The yield were shown by 221.4g/1kg bag.

‘Samkang’ a new variety of oyster mushroom, fitting for the bottle culture, was bred and by mating between monokaryons isolated from MT05433 and AE1-1. In the major characteristics of fruit body, the pilei were thick and dark-gray and the pileistripes were thick and long with softness. It was great in elasticity and cohesivness of tissue as compare to chunchu-1ho. The optimum temperature for the mycelial growth was around 26~28℃ and that for the pinheading and growth of fruitbody was around 14~16℃. In the bottle culture, it was required around 26 days in incubation period and 4 days in primordia formation. The fruit body was grew vital and uniform. The yield were shown by 136.5g/bottle.

Dajoa oyster mushroom was bred in Mushroom Research Institute in 2004. This oyster mushroom was bred and cultivated one after mating single spores collected from Boonli 89-1 and ASI 2018-249. The major characteristics of the mushroom were showing a lot of pinheadings, the gray-colored and infundibuliform pileus. The optimum temperature for the mycelial growth was around 26∼28℃ and that for the pinheading and growth of fruitbody was around 15∼18℃. Incubation period were required around 24 days with bottle culture and about 21days in P.Pvinyl bag culture. The yields was shown high by 140.7g/bottle and 260.3g/P.P vinyl bag.
