选用８个平菇（Ｐｌｅｕｒｏｔｕｓｏｓｔｒｅａｔｕｓ）菌株进行不完全双列杂交，对杂交组合的菌丝生长速度、产量等１５个性状进行了配合力分析。结果表明：各性状具有不同的遗传差异和基因效应。通过配合力效应值估算，得出了８个亲本中的２个优良亲本．同时，根据特殊配合力效应值，初步评选出了理想的杂交组合。 Eight Pleurotusostreatus strains were selected for incomplete diallel crossing. The combining ability of 15 traits including mycelial growth rate and yield of hybrid combinations was analyzed. The results showed that each trait had different genetic differences and gene effects. Two good parents in eight parents were obtained by combining force effect estimation. At the same time, according to the special combining ability effect value, we initially selected the ideal hybrid combination.
