Abstract：In order to choose yeast strains with strong antagonistic activity against Monilinia fructicola,which causes peach brown rot,7 yeast strains were selected by the dural culture method from 102 yeast strains collected from 12 sampling sites in northern Xinjiang.In particular,the strain EEQS-7D was the best among these 7 strains,which reduced the growth of M.fructicola by 78.90％.The result of in vivo test illustrated that this strain could significantly reduce the incidence of brown rot on peaches by 51.83％.The strain was capable of producing protease,and the transparent circle diameter reached 34.5 mm,which indicated that EEQS-7D could inhibit peach brown rot disease mainly by secreting protease.The strain EEQS-7D was identified as Aureobasidium pullulans based on its morphological observation,physiological and biochemical determination and 26S rDNA sequence analysis.
