1985—1988年,在浙江省新昌县重病田,采用自然诱发,鉴定了国内外小麦品种及中国春小麦与苏联球茎大麦杂交后代计1322个材料。结果免疫的品种或材料有52个。发病率0.1—5.0%的有34个,5.1—10.0%的10个。不发病品种的植株内查不到内含体和病毒粒子,说明这些品种是免疫的,而不是隐症带毒品种。在浙江省小麦地方品种中,高抗品种数占供试品种总数比例为:美玉类型占54.5%,红铁钉类型占34.1%。普通小麦与球茎大麦的杂交后代,高抗的材料占供鉴定总材料数的38.1%,可见球茎大麦抗小麦梭条斑花叶病毒(WSSMV)的基因易于转移到中国春小麦上。抗病品种的抗性较稳定,年度间抗病性变化不大,但感病品种年度间因气候条件不同差异较大。
From 1985 to 1988, 1322 materials were screened out from the severe diseases in Xinchang County, Zhejiang Province using natural inducing wheat varieties at home and abroad and between Chinese spring wheat and Soviet corms barley. As a result, 52 breeds or materials were immunized. The incidence of 0.1-5.0% of 34, 5.1-10.0% of the 10. The diseased plants can not detect the inclusion bodies and the virus particles in the plants, indicating that these varieties are immune, rather than the hidden species of poisoning. Among the wheat cultivars in Zhejiang Province, the proportion of high resistant cultivars to total cultivars was 54.5% for the jade and 34.1% for the red nails. The hybrid progeny of common wheat and corm barley accounted for 38.1% of the total number of materials identified. The results showed that the gene of B. barley resistant to wheat spindle leaf spot mosaic virus (WSSMV) was easily transferred to Chinese spring wheat. Resistance of resistant varieties is more stable, little change in disease resistance during the year, but susceptible varieties of different annual climatic conditions due to differences.
