- 摘要:
- 将我国、韩国、日本及俄罗斯远东地区的SMV 株系与鉴别寄主交互接种测定其毒力。结果指出采用外国的株系鉴别寄主难以区分我国株系毒力。同样,用我国鉴别寄主也难以区分外国毒株的毒力,所测定的我国9个株系的13个代表毒株全部能侵染最抗病的鉴别寄主韩国的Buffalo和日本的Harojoy。外国鉴别寄主中只有少数对中国株系有鉴别作用,如韩国的Kuang gy o能将S3与S1和S2区分, Davis可将S1与其它株系区分。日本的タチユタカ等可将S3的多数株系与S1和S2区分,トモユタカ可区分S1与其它株系。韩国的强株系G7、及K1、K2和日本的中强株系SMV- B的毒力,只相当于我国最弱的株系S1。因此很难找出各国株系之间的对应关系。我们认为用亲缘关系较远的外国鉴别寄主鉴定我国的株系是不适合和不必要的,而采用本国当前的主栽品种作株系鉴别寄主更有应用价值。
