“…Dong et al [38] highlighted that most of the genes present in the genome of A. bisporus still do not have a characterization of their function in the development of the fungus. Other authors also mentioned that different responses in cultivation occur due to the enzymatic activity of laccase and peroxidase, as well as suitability to the environment and region [24,39,40]. In this sense, the agronomic traits were more influenced by a phenotypic question than a genotypic one, since the strains that presented the lowest genetic variability presented great differences in the yield, mushroom weight, and method of water application.…”

“…These parameters are critical for the commercialization of the final product, especially because they impact the size, weight, and classification of the mushrooms [21,22]. Different strains may also exhibit varying degrees of disease resistance [23] and produce varying amounts of enzymes [24]. However, to date, no study has compared water demand and efficiency across different genetic materials.…”

The objective of this work was to evaluate the water supply method in the cultivation of button mushroom. The strains used were ABI 18/02, ABI 18/04, ABI 19/03, and ABI 11/19. An analysis of the ITS 1 + 2 regions, widely used as a fungal barcode, was performed in order to assess the genetics. The compost was packed in 35 × 50 cm plastic boxes with 10.5 kg m−2, and the inoculum was added (1% in relation to the compost weight). Before the addition of the casing layer, in half of the boxes, 25 L m−² of water was added directly to the colonized compost, resulting in the treatment of the water added to the compost. The yield, number, and weight of the mushrooms were analyzed. A phylogenetic tree for the A. bisporus strains based on ITS sequences confirms a close genetic relationship among the different collections of this species, and additional molecular markers are required to distinguish genotypes related to superior agronomic traits. The water management methods presented similar yields, except for one strain (ABI 18/04). The ABI 18/02 and 11/019 strains were more efficient when considering the method of adding water to the compost. This study suggests that the treatment of water added to the substrate is an alternative tool for reducing the application time and labor involved and as a control treatment to reduce water use.
