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.
