    摘要:

    采用人工接种方法研究166份黄淮海地区近年来生产上种植品种及近期育成品种(系),对黄淮海地区SMV流行株系SC3、SC7、SC6、SC11以及混合4个株系的抗性进行鉴定。结果显示:对4个株系均表现抗病(中抗,高抗和免疫)的共82份,占49.4%;其中对3个株系表现高抗或免疫的32份,占19.3%;对4个株系表现高抗或免疫的23份,占13.9%。对混合株系表现抗病的108份,占65.1%。其中表现免疫的有45份,占27.1%,表现高抗的有29份,占17.5%。对4个株系和混合株系均表现抗病的62份,占37.3%;表现免疫和高抗的材料14份,占8.4%。研究结果还显示:近年育成品种对SC3、SC7株系较早期育成品种的抗性显著增强;来自河北、北京、山西的品种抗性较好,病情指数整体较低。鉴定筛选出对接种4个株系及混合株系均表现免疫的冀豆9号和石豆6号品种,可作为抗病育种的重要抗源。本研究还出现部分品种对接种4个株系和混合株系表现出抗性差异,表明SMV株系间存在着明显的互作。

    Abstract:

    The resistances of 166 soybean cultivars to prevalent strains were evaluated using manual inoculation method. These cultivars were selected from Huang-Huai-Hai and the strains were SC3, SC7, SC6, SC11 and the mix of the four. The results showed that, there were 82 cultivars resistant to the four strains, accounting for 49.4%; Among them, 32 cultivars immune or high resistance to the three strains and 23 cultivars immune to all the four strains, accounting for 19.3% and 13.9%, respectively. There were 108 cultivars resistant to the mix of the four strains, accounting for 65.1%. Among them, there were 45 immune and 29 high resistant, accounting for 27.1%, 17.5%, respectively. 62 cultivars resistant to the four strains and the mixed strains, taking up 37.3%, while 14 cultivars immune or high resistance to them, taking up 8.4%. The results also showed that, the resistance of the recently bred varieties was significantly enhanced than the early bred varieties to SC3 and SC7. Cultivars from Hebei, Beijing, Shanxi are more resistant to the strains with the lower disease index. Jidou9 and Shidou6 were immune to all strains and can be used as resistance resources in breeding programs. It is also demonstrated that some cultivars showed resistance difference after inoculated with the four and the mixed strains, indicating that there were significant interactions between strains.
