%X The genotypic populations structure of Ascochyta pinodes and Phoma pinodella was determined across a hierarchy of spatial and temporal scale by using vegetative incompatibility system as phenotypic genetic marker. Components of genetic variation within and between populations included the following values: indices of diversity H', richness (g), indices of evenness E1, E2 and E5, spatio-temporal analysis of genotypic variation (HT and HS values), pairwise comparisons of genotype diversity, distribution of VCGs across spatio-temporal scale (GST value) and analysis of variance calculated on VCGs genotype frequencies within populations. It has been found that genotypic populations structure of Ascochyta pinodes and Phoma pinodella belong to mixed population structure clonal and recombining. Three regional populations of Ascochyta pinodes and Phoma pinodella differed significantly in both of VCGs genotype frequencies and their distribution on a spatio-temporal scale indicating on the low or moderate degree of genotype migration between regions of Poland.
