摘　　要：为了明确陕西省小麦条锈菌越夏范围,通过多年调查和试验研究,结合近年来各地小麦播种面积变化情况,对陕西省条锈菌越夏范围进行了系统分析。结果表明,小麦条锈菌在陕西省能够顺利完成越夏。越夏区主要分布于陇县、太白、凤县等高海拔地区;不稳定越夏区主要分布于镇安、旬阳阳山等海拔1 400m以上小麦种植区;留坝、宁强、山阳、周至和宁陕等海拔1 400m以上区域几乎没有小麦种植,已丧失了越夏区作用,成为小麦条锈菌非越夏区。Making clear of over-summering of Puccinia striiformis f. sp. tritici （Pst） in Shaanxi province has great importance for forecasting and integrated control of wheat strip rust. Through or- ganized survey and experiments in the over-summering regions, we studied systematically the situa- tion of over-summering of Pst in Shaanxi province. The results showed that Pst could over-summer in some local regions in Shaanxi province. Altitude above 1 400 m in Longxian, Fengxian, Taibai county and the Yangshan mountains in Zhen＇an and Xunyang county were the main regions for Pst over-sum- mering. The mountains in Zhen＇an and Xunyang belonged to unstable over-summering regions and the wheat planting area was about 2 000 hm2 in 2010. There was almost no wheat cultivation in Liuba, Ningqiang, Shanyang counties where altitude were above 1400 m, so these regions had no function for over-summering of Pst.
