肺形侧耳‘杭秀2号’的选育

A new Pleurotus pulmomarius cultivar ‘Hangxiu 2’

肺形侧耳‘杭秀2号’以‘台秀57’菌株为亲本采用多孢自交育种技术选育而成。该品种菌丝生长适温26–28℃,子实体生长发育适温22–28℃。菌盖扇形,深灰色,菌盖大小平均为4.38cm×3.65cm;菌柄圆柱形,白色,直径平均为1.06cm。鲜菇蛋白质含量2.94%,氨基酸总量2.54%。示范栽培表明,‘杭秀2号’平均生物学效率为71.2%。低温刺激后,经5–6d可完成一茬菇采收。该品种具有出菇整齐、商品性好等优良性状,适于设施栽培。

Pleurotus pulmomarius ‘Hangxiu 2’ was bred from ‘Taixiu 57’ strain by multi spore selfing. The suitable temperature for mycelial growth and fruiting body growth is 26–28°C and 22–28°C, respectively. The cap is fan-shaped and dark gray, with an average size of 4.38 cm×3.65 cm;The stipe is cylindrical, white, with an average diameter of 1.06 cm. The protein content of fresh fruiting body was 2.94%, and the total amino acid content was 2.54%. The demonstration cultivation showed that the average biological efficiency of ‘Hangxiu 2’ is 71.2%. After low temperature stimulation, one crop could be harvested in 5–6 days. This variety has the characteristics of good marketability and uniform fruiting. It is suitable for high temperature and off-season cultivation.
