To develop a new cultivar of king oyster mushroom(Pleurotus eryngii), G09-21 as parental strain was selected by the method of Di-mon crossing between monokaryotic strain ASI 2824-21 derived from ASI 2824(Keunneutari No. 2) and dikaryotic strain ASI 2887(Aeryni 3). The Pe21-53(G09-21-10 x ASI 2844-9) was shown the best cultural characteristics, selected to be a new cultivar and designated as ‘Seolsong’. The ‘Seolsong’ was distinctly formed incompatibility line in the confrontation growth of parental strains Keunneutari No. 2, Aeryni 3 and ASI 2844. Analysis of the genetic characteristics of the new cultivar ‘Seolsong’ showed a different DNA profile as that of the control strains, Keunneutari No. 2, Aeryni 3 and ASI 2844, when RAPD(Random Amplified Polymorphic DNA) primer URP4 was used. The optimum temperature and pH arrange for mycelial growth were 25~30oC and pH 5~8, respectively. This new cultivar ‘Seolsong’ of fruiting body production per bottle was about 131.443.1 g which is about 102% quantity compared to that of other cultivar Keunneutari No. 2. And also the stipe is thick and long, but the number of available stipe is few. Particularly, it was tolerant of high moisture above 90% during the growth period after primodia formation. We therefore expect that this new strain will save of labor and cost of cultivation by without culling work.
