摘要
从我国北方大豆产区采集线虫土样,应用 A.M.Golden 等的方法和鉴别品种 Lee、Pickett、Peking、PI88788和PI00763等,于每年5月至9月在室外试验围内进厅盆栽鉴定。第二批鉴定的9份土样,共鉴定出大豆胞囊线虫的三个生理小种。即1号、3号和4号生理小种,其中1号小种来自辽宁省的义县和旅顺;3号小种分布在辽宁省沈阳市苏家屯、抚顺市、开原县、凤城县;黑龙江省的富裕县,内蒙古科左中旗的保康;4号小种采自山西省的太原市。
Soil samples containing nematode cysts were collected from infested
fields in Northern China.According to the procedure of Golden et al.,five
differentials,i.e.,Lee,Pickett,Peking,PI88788 and PI90763 were used
to identify the races.The results showed that a total of 9 samples could be
divided into 3 races.Among them,2 samples belonged to race 1,6 samples
to race 3,and 1 sample to race 4.
