Abstract: Lyophyllum decastes , commonly known as Luronggu, is extensively cultivated across China. It exhibits rich germplasm in China. However, the number of cultivars available for commercial production is limited, highlighting the importance of targeted breeding programs. In this study, we utilized selected breeding and SSR molecular markers to develop improved strains of L. decastes for the first time. The breeding process strictly adhered to China’s national standard for ‘Technical inspection for mushroom selecting and breeding’. It encompassed pure strain isolation, biological classification, primary screening, secondary screening, physiological performance determination, molecular characterization, intermediate test, and demonstration cultivation. As a result, strain ZJLZS002, known for its high yield (380 ± 3.6 g·bag −1 ), shortened growth period (75.6 ± 1.3 d), and stable traits, is well suited for industrial cultivation. This new cultivar has achieved a significant milestone as the first variety in China to be officially recognized at the provincial level, under the name ‘Zhongjunluronggu No. 1’. Its development signifies a crucial advancement in achieving seed source independence and promotes the replacement of imported varieties with domestic ones, contributing to the sustainable development of China’s edible fungi industry.
