Cauliflower mushroom (Sparassis latifolia or S. crispa) is popular for food and medicine. Importance of new varieties of Sparassis was raised and studied widely by protection system of UPOV. In this study, 10 crossbred strains of Sparassis latifolia that specifically expressed distinctive features during basidiocarp formation and mycelium growth were applied to sawdust medium inoculated with S. latifolia mycelia. The 10 crossbred strains were divided into 3 groups on the basis of morphological (size of marginal wave and basidiocarp color) and genetic characteristics. Each phenotype of the parent and crossbred strains represented 3 marginal wave-sizes (large, medium, and small) and 3 color notations (NN155D, 163C, and 8D). Our result suggests that morphological characteristics of cauliflower mushroom can be affected by various environmental and genetic stimuli under artificial conditions such as crossbreed. Also this research showed genetic differences among breeding isolates and their morphological characteristics were correlated with the molecular data within parent and crossed strain.
菜花蘑（Sparassis latifolia 或 S. crispa）既是美味佳肴，又是常用药材。因其重要的经济价值，UPOV 保护体系对其新品种广泛重视并进行了深入研究。本研究以特定形态（菌盖边缘波状和菌盖颜色）和遗传特征为基础，将 10 株菜花蘑杂交菌株应用于木屑培养基上接种的 Sparassis latifolia 菌丝。根据形态（菌盖边缘波状大小和菌盖颜色）和遗传特征，将 10 株杂交菌株分为 3 组。每组亲本和杂交菌株的表型代表 3 种菌盖边缘波状大小（大、中、小）和 3 种颜色标记（NN155D、163C 和 8D）。本研究表明，在人工条件下，如杂交，菜花蘑的形态特征可能会受到各种环境和遗传刺激的影响。此外，该研究还表明，在育种种群之间存在遗传差异，其形态特征与亲本和杂交菌株的分子数据相关。
