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。

Abstract:

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.
