Fungi of the genus Pleurotus, in particular, species Pleurotus ostreatus (common oyster mushroom) are among most cultivated fungi in the world. Due to intense rates of development of studies in this field, efficient breeding programs are highly required in the search for new P. ostreatus strains. The principal traits used worldwide for selecting strains are intensity of fruitbearing, fruit body cap color (for some consumptive markets), and mycelium growth rate. In this connection, the objective of this work was to study these quantitative traits and to find molecular markers, which could be employed to accomplish breeding programs. In general, we found 12 genomic loci (quantitative trait loci, QTLs) controlling mycelium growth rate of oyster and six QTLs responsible for the fruit body cap color. The genetic map of P. ostreatus was constructed, and all markers of quantitative traits found by us were located on this genetic map. The obtained linkage map can be a useful tool for the accomplishment of breeding programs to improve economically important traits of oyster mushroom.
侧耳属真菌，尤其是糙皮侧耳（平菇），是世界上种植最为广泛的真菌之一。由于该领域研究的迅猛发展，在寻找新的糙皮侧耳菌株时，高效的育种计划至关重要。全球用于筛选菌株的主要性状包括结实强度、子实体菌盖颜色（针对某些消费市场）以及菌丝体生长速率。在此背景下，本研究的目的是对这些数量性状进行研究，并寻找可用于完成育种计划的分子标记。总体而言，我们发现了12个控制平菇菌丝体生长速率的基因组位点（数量性状位点，QTL）以及6个决定子实体菌盖颜色的QTL。构建了糙皮侧耳的遗传图谱，我们所发现的所有数量性状标记均定位在该遗传图谱上。所得的连锁图谱可为实施育种计划以改善平菇的重要经济性状提供有用的工具。
