摘要
近几年云南蔗区甘蔗花叶病大发生流行,主要原因是存在复杂性病毒病原;田间多个主栽品种高度感病;气候异常、高温少雨天气较突出以及植期多样化、引种频繁、长期连作、宿根栽培和无性繁殖等不良气候和不适栽培条件。文中提出云南省今后甘蔗抗病育种目标和甘蔗花叶病的控制对策。
In recent years, sugarcane mosaic disease has prevailed at large in Yunnan sugarcane area. There are several chief causes that induced prevalence of the disease including the complicated pathogens, the main cultivated varieties that are susceptible to the disease, the abnormal climate with high temperature and few rain standing out, the diversification of cane planting period, introduction frequency of cane seed, continuous cropping cane for long time, ratoon cultivation and clonal propagation of cane. In this paper, the aim of breeding for sugarcane mosaic disease resistance and the control strategies for sugarcane mosaic disease were put forward.
