Abstract

Since development of the first Korean button mushroom cultivar ‘Sae-Ah’ in 2010, mushroom farmers have demanded an improved cultivar. Although a new cultivar, ‘Saejeong’, was developed in 2011, this cultivar has thus far been difficult to cultivate in typical mushroom farms. To solve this problem, another new cultivar, ‘Saedo’, was developed in 2012. This new cultivar was selected by genetic analysis from crossing the heterokaryon line A175 and the homokaryon line ASI1346-15. The heterokaryon A175 was a crossed line between strains ASI1038-211 and ASI1346-20. The mycelium of ‘Saedo’ showed good growth on compost dextrose agar at 25oC. The morphological traits such as the pileus (cap) and stipe of the ‘Saedo’ cultivar were thicker than those of the reference control ‘Saejeong’, and the production yield was increased by 1.89-fold compared to that of the reference control. A field experiment of the ‘Saedo’ cultivar has been ongoing since 2013. The yield of the ‘Saedo’ cultivar was found to be substantially higher than that of the reference control during the 2 flush.
