甘蔗主要病害抗病遗传育种研究进展

Progress on Disease-resistant Breeding of Major Diseases in Sugarcane

甘蔗生产长期受到病害的严重影响,这些病害不仅降低蔗茎产量和糖分,还影响宿根性,甚至造成品种种性退化,而抗病品种的选育是保证甘蔗生产的有效途径。概述了甘蔗花叶病、黑穗病、宿根矮化病和梢腐病4种主要甘蔗病害在病原物检测、种质筛选和基因工程技术等抗病育种工作方面的研究进展。

Sugarcane production has been severely affected by diseases, which not only cause losses of yield and sugar content but also affect perennial root and even cause variety degeneration. Cultivating disease-resistant variety is the economic and effective way to ensure sugarcane production. The progress on disease-resistant breeding including pathogen detection, germplasm screening and genetic engineering of sugarcane mosaic disease, sugarcane smut, ratoon stunting disease and pokkah boeng disease were discussed.
