为了弄清广西栽培蕉和野生蕉资源材料对香蕉枯萎病的抗性情况,2001-2007年,我们对广西产蕉区县和有野生蕉类分布的主要县市的蕉类枯萎病发生情况进行了较大范围的调查;同时采用香蕉枯萎病1号生理小种接种鉴定,发现广西栽培蕉的红蕉、黄心西贡蕉、白心西贡蕉、鸡蕉、大蕉均有不同程度发病,发病率在4.9%~87.3%,而广西目前栽培的威廉斯、巴西、广东1号、广东2号、那龙本地香蕉、浦北本地香蕉及广西野生蕉资源材料未见发病,未分离到与原始病源菌株相同的病原菌。
In order to understand the resistance of Guangxi cultivated banana and wild banana resource materials to the banana wilt disease, from 2001 to 2007, we conducted a survey of banana wilt disease in the banana counties and the main counties with wild banana distribution in Guangxi A large range of surveys were carried out. At the same time, the inoculation identification of physiological races of Banana Fusarium wilt No. 1 was carried out. It was found that the red banana, yellow heart Xigong banana, white heart Xigong banana, chicken banana and plantain of cultivated banana of Guangxi all had different degrees of incidence and incidence The rates ranged from 4.9% to 87.3%. However, no cultivated materials such as Williams, Brazil, Guangdong No.1, Guangdong No.2, Nalong native bananas, Pubei native bananas and Guangxi wild banana cultivars currently cultivated in Guangxi did not separate from the original ones Pathogenic strains of the same pathogenic bacteria.
