Abstract：‘Weisheng No.1’is a new cucumber rootstock F1 hybrid bred by crossing S0703 as
female parent with S0704 as male parent. It has stronger graft compatibility and symbiotic affinity．
When grafted with cucumber scion，its seedling has high survival rate．Grafted seedlings are highly
resistant to seedling damping-off，resistant to downy mildew and Fusarium wilt. Especially after grafting
with cucumber，its fruit has shiny green skin，and the fruit is straight up．All these have obviously
improved its external appearance quality．At the same time，the contents of soluble sugar in cucumber
fruit is increased. Grafted seedlings can yield 11.49% higher than self-rooted cucumber，and 8.32%
higher than grafted with‘ Heizinangua’．It is suitable to be cultivated in open field in northern China，
and protected facility grafted with cucumber.
