Abstract:

In order to identify suitable primary varieties of Morchella for the rice-mushroom rotation system in the Taihu Lake region, this experiment utilized domestically cultivated varieties: Morchella conica (MT30), Morchella importuna (M20-1), Morchella sextelata (MH6), and Morchella septimelata (Mel-7). A systematic comparison was conducted on agronomic traits, yield, growth status, developmental stages, and appearance. The results showed that the appearance of MH6, MT30, and M20-1 met the standard for premium-grade mushrooms, while Mel-7 was classified as off-grade. In terms of yield, MH6 performed the best, achieving a cumulative yield of 3 385.0 kg·hm-2, which was primarily attributed to its significantly (p<0.05) higher fruiting body number. Furthermore, MH6 exhibited an earlier first harvest time, being 11.5-17.5 d ahead of the other varieties, and its harvesting period was extended by 8.5-14.8 d. Based on a comprehensive evaluation of appearance grade, yield and harvesting performance, Morchella sextelata (MH6) is the most suitable variety for promotion within the rice-mushroom rotation system in the Taihu Lake region.
