大豆品种资源抗花叶病毒的评价

人工接种鉴定栽培春大豆15OO余个品种(品系),野生大豆1000余份。未发现免疫的,抗病材料也甚少,栽培品种仅占2％左右,野生大豆都不抗病。栽培大豆比半野生豆抗病,半野生豆比野生豆抗病。栽培品种的苗期抗性与成株期抗性基本一致。有少数栽培品种材料兼抗褐斑粒。

EVALUATION OF RESISTANCE TO SMV IN SOYBEAN VARIETY RESOURCES

ABSTRACT More than 1500 cultivated Varieties (or lines) of Spring Soybean and 1000 wild Soybean lines were identified by artifitial inoculation with SMV. None of these cultivars were immue, and 2％ resistant material of cutivated varieties were identified only. None of wild Soybean material were resistant. Cultivated varieties were more resistant to SMV than semi—wild Soybean, and the semi—wild species more than wild soybean, Resistance of cultivars at seedling Stage was consistent with growing stage. A few of cultivars were also resistant to seed—mottling.
