四川九株松树火烧地羊肚菌驯化栽培

Nine wild Morchella strains collected from pine forest post-fire area in Yajiang County, Sichuan Province were identified and domesticated. Based on morphological observation and DNA sequence analysis, the tested strains were identified as Morchella eximia. On PDA medium, strain 6278 showed the fastest mycelial growth and formed the most quantity of sclerotia; mycelial growth of YJ082186 was the slowest, and 6288 did not form sclerotia. Under the current cultivation mode, 6751-1 had the highest yield (1.33 kg/m2), and 6288 was next in yield (1.31 kg/m2). Among the nine strains, 6288 showed the best commercial traits, while YJ082176 has the highest density of fruiting, and the basidioma average size of 6283 was the largest. This study laid a foundation for the screening and breeding of M. eximia cultivars.
