Abstract Taking different cucumber（Cucumis sativus L.）rootstock as test material, we
studied the effect of rootstock grafting on cucumber yield, quality and resistance to Fusarium wilt. The results showed that the fruit yield of‘Luhuanggua No.3’grafted by 10 different rootstocks could be increased by 40.3 %-68.3 %, among which the yield increasing effect of cucumber grafted by‘Shenli No.1’was the best,‘Huangzhen No.3’,‘Xindongli’ and ‘Anamu’took the next place, with yield increasing 50.5 %- 57.5 %. The quality of cucumber with rootstock grafting had no significant effect on cucumber quality, but the contents of VC in ‘Anamu’ and ‘Huangzhen No.4’ were significantly increased. Differences between the rest rootstock grafts and own-rooted seedlings were not significantly. The contents of soluble sugar in ‘Genglishen’, ‘Wolilong’and ‘Huangzhen No.4’ were significantly decreased. But differences between the rest rootstock grafts and own-rooted seedlings were not significantly. The nitrate contents and soluble protein in rootstock grafts were almost the same as that in own-rooted seedlings. Incidence of Fusarium wilt of the rootstock grafted was 0-8.3 %, which was obviously lower than the own-rooted（29.5 %）. As a result,‘Shenli No.1’and‘Huangzhen No.3’are firstly considered as rootstock varieties, and‘Xindongli’and‘Anamu’are taking the second place.
