| Abstract: | Mating type factors in 32 strains of Lentinula edodes collected from mountainous region of Hubei Province without dissemination of spores of cultivated strains were determined by the mating test between spore monokaryons and protoplast monokaryons derived from binuclear mycelia. In addition, analyses of the mating type ratio of protoplast monokaryons and spore monokaryons and the distribution frequency of specific mating factors in the samples were made with statistical methods. The results indicated that both the expected 1:1 ratio of mating types of protoplast monokaryons and the expected 1:1:1:1 ratio of mating types of spore monokaryons were obtained in most of the strains. 52 distinct A factors and 55 distinct B factors were determined from the sample and the series of both the specific A factors and B factors were randomly distributed. The replication frequency of mating factor in wild strains was much lower than that in cultivated strains. It meant that there was abundant germplasm resource in the natural population of Lentinula edodes. Therefore, it was important that the wild strains be served as the primary breeding materials for improving genetic variability of commercial strains of Lentinula edodes. |
