摘　　要：2015年笔者对广西甘蔗品种区域试验主要病虫害发生程度进行了初步调查。结果表明,螟害枯心苗率为0-30.60%,黑穗病发生率为0-41.52%,花叶病发生率为0-5.51%。南宁试点螟虫为害严重,甘蔗枯心苗率显著高于其他试点。各试点宿根蔗黑穗病发病率显著高于新植蔗。河池试点参试材料黑穗病发生率相对较低。桂辐06-156和桂糖07-494感染黑穗病的几率显著低于对照,可以考虑选择作为黑穗病抗性育种的亲本材料。参试材料在各试点花叶病的发病较轻。其中,桂糖05-3846的花叶病发生率最高仅为1.09%,可以考虑选择其作为花叶病抗性育种的亲本材料。Major disease and insect pests on sugarcane varieties in the regional trial plots in Guangxi were investigated in2015. The results showed that dead heart rate caused by sugarcane borers was 0-30.60%, disease incidence of smut was0 -41.52%, and disease incidence of mosaic was 0 -5.51%. In the regional trial plots of Nanning city, sugarcane was severely damaged by borers, dead heart rate was significantly higher than those in the other regional trial plots. Incidence of smut on ratoon cane was significantly higher than new planting cane in every plot. Smut rate of materials was relatively lower in Hechi city plots. Risk of infect smut of Guifu 06-156 and Guitang 07-494 was significantly lower than control, itcan be both considered to choose as smut resistance breeding parent material. Disease incidence of mosaic on materials was lighter in every plot, in which highest incidence of mosaic on Guitang 05-3846 was only 1.09%, so it can be considered to choose as mosaic resistance breeding parent material.
