Abstract: ‘Jihuang 1’is a new Sanghuangporus vaniini cultivar developed through systematic breeding. Its pure strain was obtained by isolating,purifying and culturing the fruiting bodies of wild Sanghuangporus collected from the forests of Quanshidong Forest Farm,Bajiazi Town,Helong City,Jilin Province.When cultivated on log substrates,its fruiting bodies grow singly,showing a horseshoe shape with a convex middle part. They are yellow-brown in the middle,yellow at the edges,and have a dense texture. The fruiting bodies have tube layers on the ventral surface,with a clear distinction between the ventral and dorsal surfaces. The three-year-old fruiting bodies have a diameter of 15-20 cm,a base thickness of 8-10 cm,and an edge thickness of 1-2 cm. The average yield of fruiting bodies from log cultivation is 54.54 g · kg^-1. The fruiting bodies contain 1.60% polysaccharides,15.84% flavonoids,and 3.01% triterpenoids. It has good contamination resistance during the mycelium growth period,and shows strong disease resistance with no obvious miscellaneous fungi during the fruiting period.
