摸拟自然病田的发病条件,建成可以调节水分和限制病水流窜的人工病圃,并有利于抗旱和排除积水。用麦粒菌种培养物接种,发病均匀且重。按抗性分级标准经方差分析均达极显著差异。1982-1984年已经鉴定的种质资源620个,表现抗性的23个,其中经过三年连续鉴定表现抗性稳定的有五个,这些都可供作抗性育种亲本。 Simulate the onset of natural disease conditions, build artificial nurseries that regulate moisture and restrict the flow of water and help fight drought and eliminate stagnant water. Inoculation with the wheat germ culture, the incidence of uniform and heavy. By resistance analysis of grading standards by analysis of variance were extremely significant differences. Of the 620 germplasm resources identified in 1982-1984, 23 were resistant, of which 5 were stable after three years of continuous identification, all of which were available as resistant breeding parents.
