Four Ganoderma lucidum strains, Chizhi 05, Jingda, Huizhou and Xinzhou, were screened out as hybrid parent in order to establish G. lucidum cross breeding system that based on protoplast monokaryogenesis method. Monokaryotic strains of each parental strains were obtained and mating type of each monokaryotic strains were determined. One to three monokaryotic strains that have different mating types were mated, and hybrids were identified by clamp connection observation and antagonist response. The results showed that the number of monokaryon came from Chizhi 05, Jingda, Huizhou and Xinzhou was 9, 14, 40 and 38, respectively. Only one mating type was obtained from Jingda, and two mating types were obtained from the other three strains, Chizhi 05, Huizhou and Xinzhou, respectively. Chi-square test showed that the ratio of two mating types of the three strains was 1:1. Fourteen monokaryotic strains of different mating types from 4 parental strains were select as a cross- breeding materia, and 17 hybrids were obtained, which were identified by clamp connection observation and antagonist response. This study proclaimed that the practicality of the hybridization breeding of G. lucidum by protoplast monokaryogenesis method.
