Abstract
|
|
|
|
The characteristics of monosporous isolates of winter mushroom [Flammulina velutipes (Curt. ex Fr.)] were investigated to obtain useful breeding materials. Within monokaryons from cultivars which have a white colored fruitbody showed narrow genetic variation, while domestic strains which have a brown colored fruitbody showed wide variation. The mating type of the white strains was A1A2B1B2 genotype, but that of the domestic brown strains were A3A4B3B4. In intra-crossing, the genetic stability of dikaryons mated by monokaryons from white strain was less than that of parents. While in brown strain, dikaryons with high yield and color variation were obtained.
