| 摘 要： | 为明确新甘蔗品种对甘蔗螟虫的抗性水平,以期为抗虫品种的推广应用和抗性基因发掘奠定基础,本文采用螟虫自然种群接虫方法,连续2年对10个甘蔗新品种进行了苗期螟害分析与抗螟虫性评价。结果表明,不同甘蔗新品种对螟虫抗性存在显著差异,桂糖29号、桂糖31号等较抗虫,福农39号、德蔗03-83和云蔗05-49等较感虫。部分甘蔗品种抗性会随螟虫选择压力不同而变化,云蔗03-194、云蔗05-51、云蔗06-407等在螟虫虫口密度高时表现为感虫,而在虫口密度低时表现为抗虫。

Resistance Evaluation of Sugarcane New Varieties to Borers in Sugarcane Seedling Stage |
| |
| Abstract: | Quantification of resistance to borer pest damage in sugarcane varieties is key to application of insect-resistant varieties and discovery of insect-resistant genes. Using natural population inoculation, two years surveys was conducted to analysis the borer damage in 10 new sugarcane varieties at seedling stage and their resistance to borer. The results showed that the borer resistance of different new sugarcane varieties had significant difference. Guitang 29 and Guitang 31 exhibited resistance to borer, and then Funong 39, Dezhe 03-83 and Yunzhe 05-49 were susceptible to borer. Resistance of some new sugarcane varieties varied with the selection pressures of borer. Yunzhe 03-194, Yunzhe 05-51 and Yunzhe 06-407 were susceptible to borer under higher population density of borer, however showed resistant under lower population density. |
