自1982年以来对绵阳系小麦品种在全国各地抗条锈性变异监测结果表明。1985年始见“小麦抗条锈变异观察圃”中绵阳11和繁6成株期发病。1991年,在四川省部分地区发现绵阳系小麦田间成株期感病。从田间采集的标样中,分离获得对Hy-brid46有稳定毒力的新致病菌系,该菌系毒性基因谱宽于条中29号,对主要生产品种和抗源材料如洛夫林系、繁6、特德、钱保德、伊利亚、绵阳系等有很强的毒性。 Since 1982, Mianyang Department of wheat varieties across the country showed that the variation of resistance to stripe rust. In 1985, see the “Wheat Stripe Variation Observation nursery” in Mianyang 11 and Fan 6 adult plant disease. In 1991, Mianyang wheat was found to be susceptible to adult plants in some areas of Sichuan Province. From the field samples collected from isolated, Hy-brid46 was isolated and stable virulence of the new pathogenic strains, the strains of virulence gene spectrum wider than Article 29, the main production varieties and anti-source materials such as Lovrin Department, Fan 6, Ted, Qian Bao De, Iliya, Mianyang Department has a strong toxicity.
