| 摘 要： | 为了明确陕西省2005-2007年新育成小麦品种及高代品系对赤霉病的抗性,采用单小花接种法对531份小麦品种(系)分年度进行了抗赤霉病鉴定和抗病性分析.结果表明,在这些材料中没有免疫材料;抗病品种(系)仅7份,占1.32%;中抗品种(系)26份,占4.90%;其余498份品种(系)均表现中感～感病,所占频率达93.78%.所有材料发病率均为100%.2005和2006年采用田间人工诱发接种的方法对344份材料的鉴定结果表明,抗病材料37份,占10.76%,发病率为3.3%～20.0%;中抗材料50份,占14.53%,发病率为13.3%～66.7%;中感～感病材料257份,占74.71%,发病率为23.3%～100.0%.由此可见,陕西省新育成小麦品种及高代品系对赤霉病的抗性普遍较差.建议根据各地赤霉病发生程度,选择适度抗性指标,结合现代生物技术,逐步提高新育成品种(系)抗赤霉病水平.

| Abstract: | Wheat scab is one of the important diseases in China,and growing resistant varieties is the preferred way for control of this disease.To determine the resistance of new wheat varieties(lines) in Shaanxi province during 2005-2007,531 varieties(lines) were identified by artificial inoculation.The results showed that there were no immunity varieties,and 7 varieties(lines) were resistant with ratio of 1.32%;26 varieties(lines) were middle-resistant with ratio of 4.90%;the remained 498 varieties(lines) were midd... |
