摘　　要：广西地区番茄生产除青枯病、枯萎病和根结线虫为害严重外,近两年大面积暴发番茄细菌性髓部坏死病。本试验采用田间抗性鉴定方法和分子标记技术,对20份番茄砧木材料进行对比、鉴定,筛选抗番茄细菌性髓部坏死病的多抗砧木材料。结果表明,砧木材料T034和T103不但对青枯病、根结线虫、枯萎病具有良好抗性,而且对番茄细菌性髓部坏死病表现出优良的抗性,属于聚合多抗材料。Recently,a mass outbreak of tomato bacterial pith necrosis occurred in Guangxi,except bacterial wilt,Fusarium wilt and root-knot nematode.This experiment compared and identified 20 pieces of tomato rootstock material from Guangxi,and screened rootstock material with multi-resistance to tomato bacterial pith necrosis.The results indicated that rootstocks T034 and T103 were not only resistant to bacterial wilt,Fusarium wilt and root-knot nematode,but also to bacterial pith necrosis,belonging to multi-resistance polymerization material.
