近3年黄淮南片小麦品比试验赤霉病抗性分析

Analysis of Resistance to Scab in Comparison Test of Wheat Varieties in the Past Three Years

黄淮南片麦区是我国第一大麦区,受大陆季风气候的影响,农业灾害频繁发生。在小麦生产所面临的各种病害中,小麦赤霉病的发生具有愈来愈严重的趋势。研究表明,培育赤霉病抗性品种是控制小麦赤霉病最经济、最环保和最行之有效的措施。分析近3年黄淮南片小麦品比试验共计525个参试品种的赤霉病抗性鉴定结果,抗病小麦品种22个,比例4.19%,感病小麦品种503个,比例95.81%。近3年小麦参试品种赤霉病的抗性水平仍以感和中感为主。

The south of Huang-huai wheat zone is the largest wheat region in China.Influenced by the continental monsoon climate,agricultural disasters occur frequently.The occurrence of wheat scab is becoming more and more serious among all kinds of diseases in wheat production.The results showed that the most economical,environmental friendly and effective way to control wheat scab was to cultivate scab resistant varieties.By analyzing the identification results of resistance to scab of 525 wheat varieties in the past three years,22 resistant wheat varieties(4.19%)and 503 susceptible wheat varieties(95.81%)were identified.In the past three years,the resistance level of wheat varieties to scab was mainly susceptible and moderately susceptible.
