赤霉病对长江中下游地区的小麦生产威胁很大,在大流行年份往往引起严重损失.建国以来,特别是无产阶级文化大革命以来,在毛主席革命路线指引下,对于赤霉病的发病和流行规律,以及在农业防治方面,做了不少工作,取得了一定的进展.但在选育抗赤霉病品种方面,工作做得很少,现在生产上应用的品种多数不能抗病.有些抗病品种,主要是地方品种,由于农艺性状不够好,不能适应生产发展的需要,而一般新选育或新引用的品种,又不抗病.如本所在文化大革命前选出的早熟品种“矮秆早”,当时认为早熟性和丰产性是比较好的,文化大革命中进行了推广,但由于感染赤霉病很重,不久在生产上就停止了应用.
Since the founding of the People’s Republic of China, especially since the Great Proletarian Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, scab has a great threat to wheat production in the middle and lower reaches of the Yangtze River, Epidemiology, and prevention and control of agriculture, a lot of work has been done and some progress has been made. However, there is very little work in breeding anti-scab varieties, and now most of the varieties used in production can not resist disease. Some Disease-resistant varieties, mainly local varieties, due to agronomic traits are not good enough, can not adapt to the needs of the development of production, but generally new or newly quoted varieties, not disease-resistant.If the pre-Cultural Revolution selected early varieties “ Dwarf as early as ”at that time was considered premature and high yield is better, the Cultural Revolution was promoted, but due to severe scab infection, and soon stopped production in the application.
