Positive significant correlation between three infection indexes and SDD, and negative insignificant correlation between infection indexes and LIP were found. Fifteen sugarcane varieties could be divided into 6 groups on the basis of the distance more than 1.0. It resulted most ot tested sugarcane varieties had similar smut resistance. It suggested that smut race 1 and race 2 were included in inocula and the condition for Ustilago scitaminea infection was suitable in the crop season by setting up the standard varieties of NCo310, F134, NCo376 and Ya71-374 for smut identification. In addition, the results of sugarcane varieties resistant to smut race 1 and race2 were known by only a simple field trial.

结果显示：9个引进甘蔗品种中，ROC26属于感病品种，其余属于抗病或高抗品种；3个病情指数和持续发病期的两两相关均为显著正相关，潜伏侵染期与这些参数的相关为负相关，但未达到显著水平；在类间距离大于1.0的条件下，可将15个品种聚为6类，进一步明确了各品种抗黑穗病性的相似程度；抗性鉴定标准对照种NCo310、F134、NCo376和Ya71-374的应用，明确了接种源为小种1和小种2，通过一次接种试验，明确了供试品种对2个小种的抗性水平，标准对照种的抗性表现，还说明了本生长季发病条件基本是适宜的。
