This paper studied preliminarily the relations among the percentage of diseased plants, the percentage of diseased stems and a hundred stems' disease-spot length of the rape sclerolimose in the Jianghuai hills district,Anhui Province,and also investigated emphatically the occurrence of the rape sclerolimose on the stems. For estimating the percentage of diseased stem and a hundred stems' disease-spot length, their linear regression equations were been made to simplify the survey of the rape scleroliniose in rape fields.
