摘要
自1985年将大豆花叶病毒(SMV)分为三个株系群后,最近几年又收集了149个毒株继续研究,发现原为一个株系群的毒株间在某些重要大豆品种上的症状反应有很大差别,症状严重度可相差三个级别。因此,有必要将原来的一个株系群再分为两个株系。SMV毒株间的理化稳定性有一些差异,即使在一个株系内也不一样。 作者对SMV株系间的交互保护反应进行了多次试验,株系间不一定都有交互保护反应。
Since SMV was classified into 3 groups in 1985 we have found that isolates it) one strain group had significant differences in symptoms, their severities may differed as great as 3 grades. Additional 149 isolates had been collected recently and studied. The results showed that each strain group had to be divided into two strains.There was obvious cross protection among strains, but not all of them. The degree of cross protection varied with different treatments of inoculations and different combinations of isolates.
