| 摘 要： | 在1996和1997年,在温室采用卵接法和病土接种法,测定65份烟草种质资源对南方根结线虫1号小种和爪哇根结线虫的抗病性。其中,16份抗南方根结线虫1号小种,25份中抗南方根结线虫1号小种;仅有Va102中抗爪哇根结线虫;经田间试验测定10份烟草种质资源对花生根结线虫2号小种的抗病性,CF954对花生根结线虫2号小种表现中抗。本文还研究了卵接法和病土接种法对测定品种抗性的差别,结果表明二者无显著差异。

| Abstract: | During 1996 1997,65 entries of tobacco were evaluated for resistance to Meloidogyne incognita race 1 and M.javanica in greenhouse,which were inoculated with eggs or infected soil.16 entries of tobacco germplasm were resistant to M.incognita race 1 and 25 entries were moderately resistant to M.incognita race 1.But only Va102 was moderately resistant to M.javanica. 10 entries of tobacco germplasm were evaluated for resistance to M. arenaria race 2 in field experiments.The result showed that only CF954 was moderately resistant to M.arenaria race 2. |
