General objectives of genetic improvement of cucumber

The main objectives of cucumber genetic improvement are based on known work on varieties like long, slicer, beith-alpha and rootstock.

Our genetically enhanced varieties show resistance to the following viruses: CYSDV, CVYV, CMV, PM, Ccu and Cca.

Our research and development tasks are oriented to target markets in America, Europe, Middle East and Maghreb.

Resistances that we work on Cucumber

One of the main strategies of our improvement program is the gradual introduction of virus resistances in our genetic material, and always taking into account vegetable characters of business interest.

 

INTRODUCTED RESISTANCES

ResistanceInbreedsDescription
CYSDV (Two origins)   Yellowing of cucurbits
CVYV   Yellow vein virus
Pm   Powdery mildew
CMV   Cucumber mosaic virus

DEVELOPING RESISTANCES

ResistanceSourceDescription
Fusarium C. Sativus Introduction in elite lines
DM (mildew) C. Sativus Introduction in elite lines
N (Nematodes) C. Sativus Introduction in elite lines

Lines of Cucumber

We combine classic and modern selection methods including experiments of resistance to CYSDV and Pm in natural environmental conditions of infection, which show high levels of resistance in our material.

New projects for improvement of Cucumber

Our new objectives are rootstocks, diversification and creation of new lines for other markets.
