Studies in all three agroclimatic regions of Belarus have allowed us to obtain more then 100 isolates of B. cinerea causing gray mold of many plants. The isolates were shown to belong to the three cultural-morphological groups such as mycelial, sporulating and sclerotial. Mycelial isolates (48.5%) concerned by some researchers as the high pathogenic group prevail over other two groups. Nutritive substrate was proved not to determine the formation of strictly definite morphotype. The rate of radial growth of B. cinerea colonies reveals no correlation with morphological peculiarities of these. Strict regularities in the forming of spores and sclerotia were not established when characterizing isolates from different cultural groups what indicates the presence of transitional forms between detected ones. Thus, population of B. cinerea in Belarus conditions is morpho-physiologically diverse.
