不同品系对小麦白粉病的抗性鉴定

Identification of resistance to wheat powdery mildew in wheat races

通过田间自然发病和人工接种鉴定 ,对 2 0 0 0年华北北部 2 0 3份材料中选育出来的抗病性、丰产性好的 4 8份材料再次进行成株期和苗期抗白粉病鉴定 ,鉴定结果 :成株期免疫材料有 2 4份 ,高抗材料 9份 ,中抗材料 6份。苗期无免疫材料 ,高抗材料 31份 ,中抗材料 10份。

The result showed that there were 24 immune materials,9 high resistance materials and 6 middle resistance materials at the period of wheat maturity .Meanwhile there were 0 immune material,31 high resistance materials and 10 middle resistance materials at the period of wheat seedling .
