F8815和F8817是以“三明一号”为出发菌株,选用菌丝原生质体为诱变材料,经γ射线辐射诱变,从双核再生株中选育出来的。这是食用菌中首例采用原生质体诱变方法选育成功的新品种。几年来在多省市批量生产(500多万袋)证明,其高产、优质、抗逆力等性状稳定,经济效益显著。1992年12月该项研究通过部级成果鉴定,现将主要性 F8815 and F8817 are “Sanming No. 1” as the starting strain, the use of mycelium protoplasts as mutagenized material, mutated by γ-ray radiation, bred from the dual-nuclear regenerated strain. This is the first case of mushroom edible protoplast mutagenesis breeding new varieties. In recent years, mass production in more provinces and cities (500 million bags) proved that its high yield, high quality, resilience and other traits stable, significant economic benefits. The research passed the ministerial level appraisal in December 1992 and will now be of the essence
