摘　　要：比较了不同品种在乳熟期的各叶位炭疽病发生程度和不同抗炭疽病性分级方法的准确度，并进行了高感对照筛选．结果制定了以株为基本取样单位的炭疽病分级标准，确定了以矮子高梁为高感对照的品种抗炭疽病性分级标准．In this paper, milk stage sorghum anthracnose rating index of each position of leaf and accuracy of resistant index were compared, and high susceptibility check variety were screened. A proposal standard for the anthracnose rating index of which basic sampling unit is individual plant, was worked out. And a sorghum variety Ai-Zi-Gao-Liang, was proposed as a standard high susceptibility check variety for resistant index.
