Improvement in Pepper

Improvement in Pepper
The main objectives of pepper genetic improvement are based on the work on varieties like blocky, lamuyo, spicy in their different colors: red, yellow and orange.

Our genetically enhanced varieties show resistance to the following viruses: PMMV, TSWV, LVT and TMV.

Our research and developing efforts are focused on the following objective markets: Spain, Maghreb and Middle East.

Resistances that we work on Pepper

One of the main strategies of our genetic improvement program has been the gradual use of resistances to viruses in our genetic material, without forgetting those agronomic characters of commercial interest.
