| 摘 要： | １９９３～１９９８年对河南省１３个主栽冬小麦品种白粉病的系统调查和抗性鉴定及评价结果表明：①河南主栽冬小麦品种中没有对白粉病免疫的品种，发病最重的是豫麦１３号，平均病指２８．９，平均ＡＵＤＰＣ值５０２；发病最轻的是郑州８３１，平均病指２．３，平均ＡＵＤＰＣ值２５。②感、抗白粉病性没有明显变异的品种占总数３８％，有明显变异的品种占６２％，其中，高感变中感的品种１个（西安８号），中感变高感的品种１个（

| Abstract: | The variation dynamic of resistance or susceptibility to powdery mildew for 13 winter wheat cultivars in Henan during 1993 to 1998 was analyzed in this paper.The results showed:(1)There were no immune cultivars.The cultivars of disease development heaviest was Yumai 13,average desease index and AUDPC has reached 28.9 and 502, respectively.(2)There were 5 cultivars no changing in resistance or susceptibility to powdery mildew.These account for 38%.The resistance or susceptibility of 8 cultivars to powdery mildew have taken place variation.These account for 62%.The reasons of resistance or susceptibility variation to powdery mildey in wheat cultivars were analyzed. |
