Abstract: ‘Lizhi 131’was developed from the hybridization of protoplast monokaryotic mycelium,using the wild Ganoderma lucidum strain‘T1’,which exhibits strong mycelial vitality and high biological efficiency as one parent,and’Longzhi 1’,known for its high triterpenoid content but weak mycelial vitality as the other parent. From 112 hybrid combinations,the hybrid strain L31（131）was screened out,which features high triterpenoid content,strong mycelial viability,and high biological efficiency. This cultivar has a high spore powder yield of 0.9-1.1 kg per 50 kg of wood,with a polysaccharide content of 2.43% and a triterpenoid content of 3.82%. It is suitable for cultivation in Zhejiang Province.
