公主岭地区小麦黄矮病毒株系的鉴定

IDENTIFYING THE STRAINS OF WHEAT YELLOW DWARF IN GONGZHULING REGION

小麦黄矮病是我国北方冬、春麦区广为发生的一种严重危害小麦的病毒病害。周广和等人用生物测定法查明在上述地区危害小麦的3种病毒株系。1970年以来东北地区曾多次发生小麦黄矮病的流行,给小麦生产造成严重损失。我们用生物方法查明1986年公主岭地区的小麦黄矮病毒属 GAV 株系,即二叉蚜长管蚜株系。

It was established that virus strain of wheat yellow dwarf in Gongzhuling Region was GAV strain by using biossary method in 1986.It was the same strain as that in Northwest Region.It was inferred that the wheat yellow dwarf virus in Jilin province would be carried by active aphids from North China,Northwest China and other regions with monsoon wind.
