广西番茄砧木多抗材料筛选

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。

Screening of Tomato Rootstocks with Multi-resistance in Guangxi

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．
