甜瓜的主要病害有黄瓜花叶病(CMV)、南瓜花叶病、蔓枯病等。尤以 CMV 为害严重,而栽培方法又难以控制,必须用抗性育种的方法才能解决。为此,作者首先培育单抗性品种,再培育多抗性品种。已经育成了抗白粉病品种。从1964年起又开展了 CMV 的抗性育种。一、在田间自然感病条件下,品种间抗性差异和分布地区 Melon’s main diseases are cucumber mosaic disease (CMV), pumpkin mosaic disease, gummy blight and so on. Particularly serious damage to CMV, and cultivation methods are difficult to control, we must use resistant breeding methods can be resolved. To this end, the authors first cultivate monoclonal antibody varieties, and then cultivate more resistant varieties. Already bred varieties resistant to powdery mildew. Since 1964, CMV resistant breeding has been carried out. First, in the field of natural disease conditions, the differences between varieties and distribution of resistance
