Resistance of 40 oat cultivars or lines in northwest area of Hebei Province to stem rust was evaluated from2011 to 2012.The mixture of oat stem rust isolates was inoculated during booting stage at two test sites.The results showed that 5 of 9 hulled oats,including‘Jizhangyan5',‘Jizhangyan2',‘Bayan1',‘Jizhangyan1'and ‘Dingyan 1',and 7 of 31 naked oats,including ‘Baiyan 2',‘Baiyan 11',‘Jizhangyou 6',‘Jizhangyou 12', ‘Huawan 6',‘Jinyan 14'and‘Yanke 1'were immune,resistant or slow infection at least at one test site.Most of them were more resistant at test site 1 with low temperature,which was thought to be in accord with the fact that most of oat stem rust resistance genes was low temperature resistant.
