RAPD Analysis of Two Genetic Families of Agaricus bisporus
应用RAPD技术分析两个双孢蘑菇遗传家系

Using Random Amplified Polymorphic DNA (RAPD) techinque, the genetic relationship of the strains of two genetic families of barious bisporus, which had been founded based on the genetic marker of isozyme, was examined. The results showed that there was obvious decreasing tendency of DNA amplification polymorphism in homokaryons; as the number of genetic generation increases, the genetic distance between progenise and the original arents from which bybrids derived increased; hybrids had more advantageous characters than those isolates obtained by tranditional mule-spore or single-spore screening.
