Under greenhouse conditions, the aggressiveness of 23 Sclerotinia sclerotiorum isolates to the common bean variety GTB Blyan and sunflower hybrid Deveda was studied. The straw method was used for inoculation of plants in 2nd trifoliate of common bean and 3rd pair of sunflower leaves. A three-day culture on PDA was used for inoculum of each isolate. The area under the disease progress curve (AUDPC) for each of the crops was calculated, as well as the average AUDPC (AAUDPC) for each isolate. ANOVA was used to establish the significance of the differences between the values of AUDPC. Sixteen of the 23 S. sclerotiorum isolates have higher AUDPC values at the sunflower hybrid Deveda compared to the common bean variety GTB Blyan. AUDPC values of 5 isolates are higher in the GTB Blyan variety, and the differences compared to the Deveda hybrid are significant. Two of the isolates showed similar aggressiveness concerning the two crops, with differences in AUDPC values not significant. Significant variation in the aggressiveness of the isolates was found both in the same field and between the different origins.

Key words: Sclerotinia sclerotiorum, Aggressiveness, Helianthus annuus, Phaseolus vulgaris.
