Wageningen UR finds rootstock for cucumber, tomato and sweet pepper with high resistance against the most important root knot nematodes
Wageningen, The Netherlands
December 29, 2011
During 5 years, Wageningen UR Greenhouse Horticulture did research to find a rootstock with high resistance against the most important root knot nematodes or Meloidogyne species in greenhouses in the Netherlands, M. incognita, M. hapla and M. javanica. The project was funded by the Dutch Ministry of Agriculture.
Rootstocks should combine resistance with good compatibility between rootstock and graft, good yield and quality.
Cucumber rootstocks meeting for the greater part these requirements are 64-10, 64-12 and Harry. However, seed production of these rootstocks was recently discontinued by the seed companies. Interbreedings between Cucurbita maxima and C. moschata are not sufficiently resistant against M. species.
In tomato best performing rootstocks are PG76, Brigeor and Big Power.
Best performing rootstocks in sweet pepper are Snooker, Capital and DRO 3413.
In general, tomato and sweet pepper rootstocks have a higher level of resistance against M. incognita and M. javanica compared to M. hapla. However, most cucumber rootstocks are more susceptible to M. incognita than to M. hapla.
