Abstract: To study the resistance of different sugarcane germplasm resources to borers, the resistance of six different sugarcane materials to borers was compared by the method of natural infection by stem borer. The results showed that, at the tillering stage, the resistance to borers was strong in‘ROC22’,‘ROC1626’, ‘HD32’and‘HD1’, while that of‘HG1’was the weakest. In the mature stage, the resistance of‘HD32’, ‘ROC22’,‘HD1’and‘ROC8029’was strong, and the resistance of‘HG1’was the weakest. In accordance with the grading standards of sugar cane borer,‘ROC1626’in the early stages of growth showed level 3 of ‘MR’, but at mature stage showed a level 5‘S’.‘ROC22’in the early stages showed level 3 of‘MR’, while in the mature stage showed a‘MS’of level 4. But the‘HD1’maintained‘MS’of level 4. Thus, different sugarcane materials showed different degrees of resistance to the infection of borers at different growth and development stages. And the same sugarcane material in different growth periods had different resistance to borers’
