小麦赤霉病在南京市郊已连续两年(1984,1985)达中度以上流行,种植抗病品种是防治赤霉病最经济有效的措施。目前抗病品种很少,且存在抗性高者产量低,而产量高者抗性就低的矛盾,因而尽快培育抗病品种是十分重要的。 关于抗赤霉病品种的利用,目前主要是抗扩展品种,如苏麦三号,宁8026等;也有极少数抗侵入的品种,如镇74—95,由于农艺性状较差,在生产上应用较少。此外,还有抗接触的避病特性品种,如江苏各地的大
Wheat head blight has been endemic for more than two consecutive years (1984 and 1985) on the outskirts of Nanjing. It is the most economical and effective measure to control the scab. At present, there are few resistant varieties and there are conflicts with low resistance and high yield, so it is very important to cultivate resistant varieties as soon as possible. On the use of varieties resistant to blight, the current main varieties are resistant to expansion, such as Sumai III, Ning 8026, etc .; also a very small number of anti-invasive varieties, such as the town of 74-95, due to poor agronomic character in the production of applications less. In addition, there are varieties of anti-contact avoidance traits, such as large ones across Jiangsu
