“…For fundamental and applied interest, the dissection of genetic architecture of mycelium growth has been carried out in edible mushrooms using QTL mapping or other methodologies (Larraya et al 2001(Larraya et al , 2002Foulongne-Oriol 2012;Sivolapova et al 2012). In this study, we used three different segregation populations to uncover the loci regulating and controlling the vegetative mycelium growth rate of L. edodes.…”

“…As for other crops, the type of genetic markers has developed from isozyme up to the now common single nucleotide polymorphic markers (SNPs; for an overview on markers used in linkage analysis in fungi, including A. bisporus see: Foulongne-Oriol 2012). May and Royse (1981, 1982) started to use isoenzyme markers to elucidate the life cycle of A. bisporus and confirm crosses between homokaryons.…”

True breeding of button mushrooms has hardly been done in the last decades, despite this species being one of the most cultivated mushrooms worldwide. Research done in the last 20 years has identified and characterised new germplasm and improved our understanding of the genetic base for some traits. A substantial collection of wild-collected strains is now available and partly characterised for a number of important traits such as disease resistance and yield. Most of the variations found in a number of important agronomic traits have a considerable heritability and are thus useful for breeding. Genetic marker technology has also developed considerably for this mushrooms in the last decade and used to identify quantitative trait loci (QTL) for important agronomic traits. This progress has, except for one example, not resulted so far into new commercially varieties. One of the reasons lies in the typical life cycle of the button mushroom Agaricus bisporus var. bisporus which hampers breeding. Joint investment is needed to solve technical problems in breeding. Special attention is needed for the protection of new varieties. Due to its typical life cycle, it is very easy to generate so called “look-a-likes” from protected cultivars by screening fertile single spore cultures. A consensus has been reached within the mushroom (breeding) industry to consider this method as the generation of essentially derived varieties as defined in plant breeding.Electronic supplementary materialThe online version of this article (doi:10.1007/s00253-017-8102-2) contains supplementary material, which is available to authorized users.

“…As in plants, fungal lines with contrasting performance are commonly crossed to generate segregating populations and used to map genomic regions involved in traits and to identify candidate genes (Foulongne-Oriol 2012). This is usually done by protoplasting the heterokaryotic parental lines and recovering the constituent nuclei as homokaryons which are subsequently used for outcrossing.…”

Multi-trait QTL analysis for agronomic and quality characters of Agaricus bisporus (button mushrooms)

The demand for button mushrooms of high quality is increasing. Superior button mushroom varieties require the combination of multiple traits to maximize productivity and quality. Very often these traits are correlated and should, therefore, be evaluated together rather than as single traits. In order to unravel the genetic architecture of multiple traits of Agaricus bisporus and the genetic correlations among traits, we have investigated a total of six agronomic and quality traits through multi-trait QTL analyses in a mixed-model. Traits were evaluated in three heterokaryon sets. Significant phenotypic correlations were observed among traits. For instance, earliness (ER) correlated to firmness (FM), cap color, and compost colonization, and FM correlated to scales (SC). QTLs of different traits located on the same chromosomes genetically explains the phenotypic correlations. QTL detected on chromosome 10 mainly affects three traits, i.e., ER, FM and SC. It explained 31.4 % phenotypic variation of SC on mushroom cap (heterokaryon Set 1), 14.9 % that of the FM (heterokaryon Set 3), and 14.2 % that of ER (heterokaryon Set 3). High value alleles from the wild parental line showed beneficial effects for several traits, suggesting that the wild germplasm is a valuable donor in terms of those traits. Due to the limitations of recombination pattern, we only made a start at understanding the genetic base for several agronomic and quality traits in button mushrooms.Electronic supplementary materialThe online version of this article (doi:10.1186/s13568-016-0239-3) contains supplementary material, which is available to authorized users.
