A new cultivar "KNR10-1" of Pleurotus eryngii was developed by the method of mono-mono crossing between monokaryotic strains derived from KNR2594 and KNR2610, respectively. The optimum temperature of mycelial growth was 25℃ and that of fruiting body development was 15 - 16℃. The period of harvesting including primordia formation of "KNR10-1" was one day faster 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 the teeth of a comb. The yield was 90±12.9g/850cc plastic bottle. The fruit body has a longer shelf life than control strain KNR2312 at 4℃. Analysis of the genetic characteristics of the new commercial strain "KNR10-1" showed a different profile as that of the control strain KNR2312 when RAPD (Random Amplified Polymorphic DNA) primers were used. This new variety of King Oyster mushroom is characterized by the improved storability after harvesting.
