We bred a new strain of Pleurotus eryngii having few number of fruit body per bottle. It’s name is ‘Saegonji’ and it wasbred by mating monokaryotic strain isolated from E12-176 and monokaryotic strain ‘aerini No.3’ in Mushroom Research Institute,Gyonggi province A.R.E.S. The characteristics of a new strain ‘Saegonji’ are as follows. The optimum temperature for mycelium growthwas from 23 to 26^oC on PDA medium and those for the primodium formation and the growth of fruit body were about 15^oC. Theperiod from spawn innoculation to harvesting required around 51 days at 20^oC. The number of fruit body per bottle was 12.8 and itwas 9.3 less than ‘Keunneutari No.2’. The length was 135.8 mm. It was longer than ‘Keunneutari No.2’, The color of cap was whitegrey, while that of `Keunneutari No.2was grey. The yield was about 159 g per bottle(1100cc) and it was same as Keunneutari No.2.
