摘　　要：本文报导了1986—1990年对甘肃省2075份小麦条锈菌标样的监测结果。共监测出23个生理小种类型。发现新小种条中29号及洛13致病类群出现频率急骤上升,导致“洛类”品种抗性广泛变异,是近年病害重新流行为害的主要因素。并就新小种类型对目前主要生产品种和抗源的致病特点进行了研究,为品种布局和抗源选用提供了具体目标。This paper reports the results of monitoring 2075 samples of wheat stripe rust during 1986-1990 in Gansu province. 23 physiologic races were identified. Results showed that the frequency of new race No. 29 and Lovrin 13 types arose rapidly and that caused Lovrin 10 and 13 types to change their resistance widely. It was found to be the major factor for spreading the disease again in recent years. The pathogenic characteristics of the main productive varieties and resources are studied. This report also presents concrete objectives for variety deployment and selection of resistance resources.
