为了解贵州小麦品种(系)在不同环境条件下的抗条锈病能力,在贵州贵阳、赫章和四川绵阳对81个贵州小麦品种(系)进行了抗病性鉴定。结果表明:在自然条件下,免疫~高抗的品种(系)为27个,约占供试品种(系)的33%,中抗品种(系)为5个,约占供试品种(系)的6%,中感~高感的品种(系)为49个,占供试品种(系)的61%。与供试材料品种审定时抗性比较,小麦各品种抗条锈病能力呈不同程度的下降趋势。
為瞭解貴州小麥品種(繫)在不同環境條件下的抗條鏽病能力,在貴州貴暘、赫章和四川綿暘對81箇貴州小麥品種(繫)進行瞭抗病性鑒定。結果錶明:在自然條件下,免疫~高抗的品種(繫)為27箇,約佔供試品種(繫)的33%,中抗品種(繫)為5箇,約佔供試品種(繫)的6%,中感~高感的品種(繫)為49箇,佔供試品種(繫)的61%。與供試材料品種審定時抗性比較,小麥各品種抗條鏽病能力呈不同程度的下降趨勢。
