초록

A new commercial strain "Dan Bi" of Pleurotus eryngii was developed by intra-specific crossing between monokaryotic spores derived from KNR2312 and KNR2596, respectively. The optimum temperature of mycelial growth was 25℃ and that of fruiting body development was 15 -16℃. The primordia formation of "Dan Bi" was one day later than that of control strain KNR2312. The color of pileus and stipe surface was neutral-brown and pure white, respectively. The shape of pileus was dome and has a scale like as cobweb. The yield was 93±4.8g/850cc plastic bottle. Analysis of the genetic characteristics of the new commercial strain "Dan Bi" showed a different profile as that of the control strain KNR2312 when RAPD primer 8001, 8002, 8003, 8004, and 8005 were used. This new variety of King Oyster mushroom is characterized by a few primordia formation after scratching. It would be of much help to mushroom cultivators in a process of culling of P. eryngii.
