Taking‘Tiemuzhen’，‘RS112’，‘Suanjieqie’，‘Qiezhen No.21’，‘Qiezhen No.31’ as
rootstocks，and‘Yuqie No.5’as scion，this paper studied the effects of different grafted rootstocks on
eggplant growth，quality and resistance to bacterial wilt．The results showed that all tested rootstocks had
stronger affinity with the scion．‘RS112’and‘Suanjieqie’as rootstocks had a better promoting effect on the
growth of grafted plants．‘RS112’as rootstock could improve fruit quality．All 5 tested rootstocks were highly
resistant to bacterial wilt．‘RS112’ and ‘Tiemuzhen’ as rootstocks could delay the occurrence of bacterial
wilt，significantly reduce disease index，and effectively prevent and control bacterial wilt．‘Suanjieqie’，
‘Qiezhen No.31’and‘Qiezhen No.21’ as rootstocks showed high susceptibility or susceptibility to bacterial
wilt．The comprehensive evaluation indicated that‘ RS112’ was the optimized rootstock for yield increasing，
disease resistance and superior quality of grafted eggplant．
