To develop a new variety of oyster mushroom(Pleurotus ostreatus), parental strains was selected bythe method of Mon-Mon crossing between monokaryotic strains derived from ASI 2596(Suhan No.3) and ASI2782(Black pileus mutant). The SB-73(ASI 2596-11 x 2782-8) was shown the best cultural characteristics, selectedto be a new variety and named as ‘Dagul’. The ‘Dagul’ was formed incompatibility line distinctly in the confrontationgrowth of parental strains Suhan No.3 and ASI 2782. The optimum temperature for mycelial growth,fruiting body development and pH arrange were 25~30℃, 14~17℃ and pH5~8, respectively. Fruiting body productionper bottle was about 68.0±24.1 g which is almost 115% quantity compared to that of other variety SuhanNo.3. And also the stipe is long and individual generation is multiple. Analysis of the genetic characteristics of thenew variety ‘Dagul’ showed different DNA bands as that of the control strains, Suhan No.3 and ASI 2782, whenRAPD(Random Amplified Polymorphic DNA) primers URP7 and Rcb1 were used. This new variety 'Dagul' of oystermushroom is characterized by multiple of individual generation and the stipe is long. We therefore expect thatthis new strain will increase of the income by cultivation of field.
