平菇数量性状遗传基础研究

Study on the Hereditary Basis of Quantitive Characters of Pleurotus Ostreatus

选用８个平菇品种及其配制的２４个自交菌株，研究了２１个数量性状的遗传变异特性。结果表明，平菇自交后代与其亲本性状的均值有明显差异，因性状和品种不同，由遗传变异引起的性状分离多少亦不同。根据各品种及其自交后代品种内和品种间变异的分析，将性状初步归为３类。产量性状、菌丝生长速度。

cultivars of pleurotus ostreatus were selected and selfed with monokaryotic strains resulting in 24 dikaryotic inbred strains. 21 quantitive characters of 32 strains had been studied, the results showed that the parental means greatly differed from that of their inbred progenies and the genetic separations were different depending on the cultivars and characters. According to the values of variation of the intra and intercultivars, the characters were divided into three groups. Some important economic traits such as yield characters, mycelial growth rate, time of first primordium appearance and length of stipe appeared their own specific genetic variation property.
