摘要
细菌性枯萎病是当前我国木薯生产中的第一大病害。比较剪叶、针刺和喷雾等接种方法 ,发现剪叶法适用于大批量的种质抗性评价。采用剪叶法完成了603份木薯种质的抗性评价,结果表明高抗种质仅有6份,绝大多数种质均表现出一定的感病性。在广东省开平市进行29份木薯种质的田间发病情况调查,结果表明华南系列、桂热系列等主栽种质均不抗病。
Bacterial blight is the most serious disease in the cassava plantations of China.The inoculation effect of three methods（leaf-cutting,needle-stabbing and foliar-spraying） were compared,and leaf-cutting was the best method for resistance evaluation of large quantities of germplasms.The resistance evaluation of 603 cassava germplasms were finished,the results showed only 6 germplasms were high resistant and most of the germplasms showed certain degree of susceptibility.The bacterial blight occurrences of 29 germplasms were investigated on Kai ping,Guangdong Province,cv.SC and GR series weren＇t resistant.
