【摘要】 在云南省内收集野生子实体,经过鉴定和组织分离获得白肉灵芝(Ganoderma leucocontextum)菌株,以菌株L4439作为对照,通过初筛、复筛、区别性鉴定、中试和多年多点示范栽培选育菌株。结果表明:选育的菌株L4968菌丝生长速度较快,子实体呈红褐色、漆样高光泽,同心环纹和放射状纵脊明显,菌盖长度为(15.08±0.12) cm,菌盖宽度为(12.23±0.09) cm,菌肉厚度为(0.81±0.02) cm,菌柄长度为(7.25±0.10) cm,菌柄直径为(2.75±0.07)cm,每袋子实体鲜重为(84.98±1.41) g,生物学效率为(15.45±0.26)%,栽培周期为(85.00±0.82) d,出菇整齐,栽培性状稳定,栽培产量较高,该菌株适宜在云南及周边地区进行设施化和林下仿生栽培。2023年,菌株L4968通过云南省种子管理站云南省非主要农作物品种鉴定,品种名称为‘云灵3号’。

【Abstract】 Wild fruiting bodies of Ganoderma leucocontextum were collected in Guishan Town, Shilin County, Kunming City, Yunnan Province, and then different strains were obtained through tissue isolation and purification. These strains were compared with the control strain L4439 for mycelial growth(preliminary screening), fruiting body development(secondary screening), and then the selected strain was further studied for antagonistic reaction with L4439, analyzed for phylogeny, and cultivated at pilot and demonstration scales at different cultivation sites. The results showed that a strain named L4968 was selected for its fast mycelial growth rate and superior fruiting body development. Fruiting bodies of L4968 were reddish brown with a high gloss paint like appearance, and they also had obvious concentric ring patterns and radial longitudinal ridges. The pileus length, pileus width, pileus thickness, stipe length, stipe diameter, fresh weight per bag,biological efficiency and cultivation cycle of L4968 were(15.08±0.12) cm,(12.23±0.09) cm,(0.81±0.02) cm,(7.25±0.10) cm,(2.75±0.07) cm,(84.98±1.41) g,(15.45±0.26) %, and(85±0.82) d, respectively. L4968 showed uniformed fruiting, stable cultivation traits, wide adaptability and high yields. It can be cultivated in facilities and under forests of Yunnan and the surrounding areas. In 2023, L4968 was recognized as a non-major crop variety of Yunnan Province, and was named ’Yunling No.3’.
