Abstract: Twenty-seven strains of Ganoderma lucidum were verified to be different strains through somatic incompatibility.The correlations of mycelial growth rate and yield,the relative activity of laccase and cellulase as well as yield were established.To further understand the roles governing growth rate during cultivation,Pearson correlation analysis was used to evaluate data from the process.Comparison of yield to that of mycelial growth rate,relative activity of laccase and cellulase demonstrated high correlation with yield.The results indicated that the correlation between these factors and yield were in high linear correlation.The model of selecting parent strains for Ganoderma lucidum hybridization breeding was constructed,which was useful and economical.

Key words: Ganoderma lucidum, hybridization breeding, multiple linear regression analysis, screening
