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．
The degree of occurrence of anthracnose and the accuracy of different anti-anthracnose grading methods in different leaf positions of different cultivars were compared, and high-sensitivity control screening was carried out. Results An anthracnose grading standard with strain as the basic sampling unit was established, and the anti-anthracnose grading standards of varieties with high sorghum as elite were determined.
