多孢自交选育大球盖菇新品种

Selection of a New Variety of Stropharia rugosoannulata by Polyspore Self-crossing

以优质大球盖菇栽培品种明大128为亲本,通过多孢自交选育获得菌丝生长势强、产量高的新菌株S18,并进行新菌株鉴定和品种区域试验。结果表明S18达到新品种认定标准,通过浙江省农作物品种认定委员会认定,定名为球盖菇18。球盖菇18的菌丝生长最适温度为18~22℃,出菇最适温度为14~25℃;子实体单生或丛生,粗壮,致密,不易破碎;菌盖半球形,黄褐色至棕褐色,有鳞片,直径为4.81~5.19 cm;菌柄圆柱形,白色,直径为3.54~3.75 cm;平均生物学效率为77.4%。具有丰产性好,品质优,商品性好等优点,适于设施栽培和林下栽培。

The high-quality Stropharia rugosoannulata cultivar Mingda 128 was taken as the parent,and a new strain S18 with strong mycelial growth and high yield was obtained through multi-spore self-crossing.The new strain was identified and the variety regional test was conducted.The result showed that S18 is up to the standard of new variety identification,and it is recognized by Zhejiang Crop Variety Identification Committee and named as Qiugaigu 18.The optimum temperature for mycelial growth is 18-22℃,and the optimum temperature for fruiting is 14-25℃.The Fruit body is solitary or tufted,stocky,pyknotic,and not brittle.The pilei are convex,thick and yellow-brown to tan,with diameter of 4.81-5.19 cm,covered with scales.The stipes are cylindrical,white,with diameter of 3.54-3.75 cm.The average biological efficiency is 77.4%.It has characteristics of high yield,good quality and good marketability.It is suitable for facility cultivation and under-forest cultivation.
