摘要 

[目的]明确广西各区试点的甘蔗螟虫为害情况及品种抗性,为品种合理布局和螟虫综合防控提供依据。[方法]2015年,在甘蔗生长前期对广西6个区试点的螟害发生情况进行实地调查。根据发生程度,利用枯心指数划分的抗性标准和聚类分析的方法对品种的田间抗性综合评价。[结果]各区试点螟害枯心率0~30.60%,枯心指数0~100.00,南宁试点的螟害发生率最高。参试品种中,未发现抗螟虫品种,中感(MS)品种6个,占50%;感虫(S)品种4个,占33%;高感(HS)品种2个,占17%。系统聚类分析结果与参试甘蔗品种的抗性表现一致。[结论]螟虫在不同区试点的发生程度差别明显,参试品种之间存在显著抗性差异,且新植蔗的螟害发生情况较宿根蔗重。

Abstract

[Purpose] In order to provide evidence for rational distribution of sugarcane varieties and synthesize prevention and control to borers, the damage of borers and sugarcane varieties resistance of regional trial in Guangxi should be determined.[Method] A survey to occurrence of borers was conducted in 6 experimental points on early growth stage of sugarcane in Guangxi in 2015. According to the incidence, sugarcane varieties resistance to borers was comprehensive evaluated by dead heart index and cluster analyze.[Results] Dead heart rate was from 0 to 30.60%, and dead heart index was from 0 to 100.00 in the whole experimental points. There was the highest incidence of borers in Nanning City pilot. In all tested varieties, resistance sugarcane variety to borers was no found, 6 varieties were of the middle sensitivity to borers (MS), accounting for 50%; 4 varieties were sensitive to borers (S), accounting for 33%; 2 varieties were high sensitive to borers (HS), accounting for 17%. The results of clustering analysis matched that the resistance performance of tested sugarcane varieties in field.[Conclusion] Incidence of borers in different sugarcane region was obviously inconsistent. Significant differences of resistance were found between tested sugarcane varieties, and the ratoon cane was damaged by borers more seriously than newly planted cane.
