Resumen
Mycelium growth rate is a quantitative characteristic that exhibits continuous variation. This trait has
applied interest, as growth rate is correlated with production yield and increased advantage against competitors.
In this work, we studied growth rate variation in the edible basidiomycete Pleurotus ostreatus growing as

Mycelium growth rate is a quantitative characteristic that exhibits continuous variation. This trait has
applied interest, as growth rate is correlated with production yield and increased advantage against competitors.
In this work, we studied growth rate variation in the edible basidiomycete Pleurotus ostreatus growing as
monokaryotic or dikaryotic mycelium on Eger medium or on wheat straw. Our analysis resulted in identification
of several genomic regions (quantitative trait loci [QTLs]) involved in the control of growth rate that
can be mapped on the genetic linkage map of this fungus. In some cases monokaryotic and dikaryotic QTLs
clustered at the same map position, indicating that there are principal genomic areas responsible for growth
rate control. The availability of this linkage map of growth rate QTLs can help in the design of rational strain
breeding programs based on genomic information. [--]
