香菇原生质体诱变育种初报

A study on the protoplast induced breeding of Lentinus edodes

香菇栽培菌株原生质体经紫外线诱变后得到 1 0 5株再生菌株 ,与亲本菌株的菌丝长速、产量和出菇期进行比较 ,部分再生菌株获得了早熟、高产的优良特性。经继代培养证明 。

The experiment was carried out to inquire about the possibility of strain selection and improvement in Lentinus edodes through protoplast formation and mutagenesis by UV.Mycelial growth rate,yield,and period of fructification of 105 selected regenerants from UV treated protoplasts were measured and compared with their parents.Several selected regenerants achieved some better qualities such as higher yield and earlier fruiting.Several repeated cultivations of these regenerants reconfirmed their new capacities.
