| 中文摘要: |
| 选用6个生产用金针菇菌种(白色品种菌株 F10、F4、FM、F21，黄色品种菌株F29、F3)分别进行自交，对其S1代自交群体的菌丝生长速度、产量、原基发生早晚、农艺性状进行综合分析。结果表明，自交导致后代群体的平均生长速度、平均产量降低。黄色自交子代菌株平均生长速度快于白色自交子代菌株。菌丝生长速度与产量不具有相关性，产量与现原基早晚有较强相关性，相同自交系中黄色品种现原基早于白色品种，F3菌株黄色后代现原基早于白色后代。在各菌株自交子代群体中，FM菌株子代具有高产优势，F3菌株子代有短菌龄优势，F10菌株子代有较好的商品表型特征，可根据育种目标选择自交子代群体中的优势菌株加以利用。 |
| 英文摘要: |
| Six cultivated strains of Flammulina velutipes were used for selfing breeding and integrative evaluation of the progenies was conducted based on mycelial growing rate, yield, primordium formation time and agronomic traits of S1 generations. The results showed that the mycelial growing rate and yield of self-bred populations was lower than that of their parent strains. Yellow strains grow faster than white strains. The yields were found to be unrelated to the mycelial growing rate, but has strong relativity with primordium formation time. In the self-bred populations, the S1 generations of white strain FM has superiority in high yield, and S1 generations of strain F3 showed superior in fast growth, while S1 generations of strain F10 showed comparatively fine in agronomic traits. These characteristics can be used for selective breeding according to different breeding purposes. |
