首次报道用原生质体融合技术对茯苓作生物工程育种，取得融合菌种，在空徽霍山县境内进行野外栽培试验的结果．亲本P₁、p₅₇₈经茯苓菌丝体原生质体分离、融合、标记和融合子检出、培养和鉴定等步骤后，制成栽培种F₁、与P₁、P₅₇₈同时进行了对比栽培。试验结果：P₁均产为0．5kg／窖，P₅₇₈为2．20kg／窖；F₁为1．73kg／窖；F₁产量介于2个亲本之间，产量不够理想，对其原因作了初步分析。

Rcsult of field cultivation test by protoplastic fusion technique for biological cngln ering breeding of Poria cocos in Huoshan county, Anhui Province was reported for the first time. A fusion strain F₁ was obtained from parents P₁, P₅₇₈ by separation, fusion, marker of hypha protoplast and identification of recombinat. It was cultivated simultaneously with P₁, P₅₇₈ for comparison. Results showed that the average cellal outputs were 1.73, 0.5 and 2.20kg respectively.As the output of strain F₁ is intermediate between its parent P₁ and P₅₇₈, the result is considered to be unsatisfactory. The reason for such result was discussed.
