茶树菇复合群系统类群及交配分析

［目的］茶树菇复合群是一类具有重要经济价值的菌类,其菌株资源多样,命名混乱。为了给育种工作提供参考依据,［方法］本研究利用线粒体小亚基V4-6-9区序列和交配,对四个代表菌株进行分子和交配特征分析,［结果］结果表明：(1)线粒体小亚基序列作为类群区分的有效标记,有效区分杨柳田头菇类群、茶树菇/茶薪菇类群和杨树菇类群；(2)交配特征显示杨柳田头菇为独立生物学种,而其它类群属同一生物学种,建议使用茶树菇这一名称。［结论］研究结果可以为茶树菇资源鉴定及育种研究提供参考 。

Systematic Group and Mating Analysis of Agrocybe aegerita Complex

Objective]Agrocybe aegerita complex, an important mushroom with high economic value, included many groups with high diversity and confusing denomination. Method]To provide scientific reference for the breeding work, molecular data of mitochondrial small subunit (mtSSU) V4-6-9 regions and mating tests were employed for the investigation on four reference stains with different designations, Result]and the results showed (1): mtSSU V4-6-9 could be used as the efficient molecular mark for distinguishing A. salicacola, A. aegerita/A. chaxingu and “Yangshugu” groups; (2) mating tests showed A. salicacola was an independent biological species, and other groups were the same biological species A. aegerita which was suggested as the general name. Conclusion]The results in this study may provide a reference for the identification and breeding program of A. aegerita complex.
