摘要：

Single ascospore isolates of the Scots pine canker pathogen Crumenulopsis sororia were sampled from each of six native pinewoods in Scotland and scored for their genotype at four isozyme loci. Gene diversity was high both within the total collection (H(T) = 0.26) and within individual populations (HBAR(S) = 0.25). Levels of genetic differentiation among populations were low (G(ST) = 0.041) and mean genetic distances between populations were small (DBAR = 0.0146). Genetic analysis of families from individual apothecia support previous suggestions that C. sororia practises random biparental outcrossing. Within populations the degree of non-random association between alleles at different isozyme loci is small. The results are interpreted in the light of knowledge about the population biology of C. sororia.
