摘要： 通过人工接种和自然感病两种方法，共鉴定寒地水稻新品种(系)292份(次)，鉴定出高抗新品种(系)22份，适合寒地稻区种植的优质、抗病、农艺性状优良的新品种（系）7份，扩大和充实了抗病基因库。

Abstract: 292 new rice varieties(lines) from cold regions were appraised by means of the artificial noculation and natural infection .The appraisal shows that 22 of the varieties(lines) have high resistance to rice blast disease and 7 of the varieties(lines) are high quality ，disease resistance and good agronomic type. These varieties can be planted in cold regions.These will expand and substantiate gene bank of disease resistance to rice blast.
