A new commercial variety "KNR12-1" of Pleurotus eryngii was developed by the method of mono-mono crossing between monokaryotic strains derived from KNR2312, KNR2594, and KNR2596. The parental strains are characterized by the property of high quality and a small number of primordia, 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 was 1.0 - 1.5 days later than that of control strain Knneutari No.3 in the culling cultivation. 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 101.7±3.5g/850cc plastic bottle. Analysis of the genetic characteristics of the new commercial variety "KNR12-1" showed a different profile as that of the control strain, Knneutari No.3, when RAPD (Random Amplified Polymorphic DNA) primer was used. This new variety "KNR12-1" of Pleurotus eryngii is characterized by the improved storability and a small number of primordia formation after scratching. It would be of much help to mushroom cultivators in a process of culling and storage of P. eryngii.
