摘要
高粱霜霉病是由高粱霜霉菌[Peronosclerospora sorghi(Weston and Uppal)Shaw]引起的一种真菌病害,能为害高粱、玉米、珍珠粟等农作物.它最早发生在亚洲、非洲的一些国家.在1949年汇总的植物病害分布图上(C. M. I. Distribution Map of Plant Diseases),还有中国和意大利.但后来没有证实.1956年,在美洲巴拿马饲料高梁上发现高粱霜霉病.不久,此病在美洲的一些国家相继传播开来.1961年,在美国得克萨斯州最先发现高梁霜霉病.1967年以后,高粱霜霉病成为美国第一个主要的作物流行病.70年代初期。
Sorghum downy mildew (SDM) caused by Peronosclerospora sorghi is an important disease of sorghum. SDM occurs in some countries of Asia, Africa and America, and damages cereal crops severely. There is no report of SDM in China. This study is to determine the reaction among some chinese sorghum to pathogen of P. sorghi and to identify the resistant sources of chinese sorghum. In 19 samples of chinese local and selected varieties, the incidence of sporulation was 96.2 to 100% and the average incidence was 98.7%. In 19 samples of chinese R-lines evaluated, the incidence of sporulation was 77.5 to 100% and the average incidence was 96.3%. The result indicated that there are no resistant resources in the tested chinese sorghum to SDM.
