大豆是我省的主要作物,大豆花叶病毒(SMV)近些年来呈发展趋势,尤以品种多而复杂的科研单位、良种场发病较重,现有生产推广品种多属感病型,由花叶病毒引起的褐斑粒普遍较重,一般在5％左右,最高可达95％以上,严重的影响了大豆品质和出口外销,据观察,品种在抗大豆花叶病毒方面有明显差异,不同品种间褐斑粒率也相差悬殊,为了明确现有大豆材料的抗病性,我所从83—85年开展了此项工作。
Soybean is the main crop of our province. Soybean mosaic virus (SMV) has been developing in recent years. Especially in scientific research institutes with many varieties and complexities, the incidence of serious breeds is relatively high. The current varieties of production promotion are mostly susceptible types. Mosaic spot caused by mosaic virus is generally heavier, generally about 5%, up to 95% or more, a serious impact on the quality of soybeans and export sales, it was observed, the varieties have significant differences in resistance to soybean mosaic virus, Between different varieties of brown speckle rate is also very different, in order to clarify the existing resistance of soybean materials, I carried out this work from 83 to 85 years.
