The results of this study were used to prepare basic data and identify research trends to help understand Korea's mushroom industry by analyzing the related research published in the final report of the Ministry of Agriculture and Forestry from 1995 to 2020. The annual research trends are as follows: 1 in 1995, 7 in 1998, 6 in 2000, 9 in 2003, 9 in 2006, 10 in 2008, 5 in 2012, 3 in 2015, 8 in 2018, and 4 in 2020. They increased rapidly from the second half of 1990 to the second half of 2010 but decreased thereafter. The research fields were as follows: quality and postharvest management (45 articles, 32.3%), cultivation and production (41 articles, 29.5%), facilities (19 articles, 13.7%), genetic breeding (14 articles, 10.1%), biotechnology (14 articles, 10.1%), and others (6 articles, 4.3%).
