DNA markers for
ToBRFV Resistance

Over the last five years, the Harmoniz R&D team has efficiently and effectively concentrated its energy, time and resources on researching ToBRFV genetic sources. Thanks to our unique trialing system, together with our focus and ability to take rapid decisions based on our results, we have succeeded in identifying DNA markers that elicit resistance to ToBRFV.

A Unique PVIS

How we certify
our seeds
ToBRFV resistant

In 2015, our breeders developed the PVIS (Plant Virus Inoculation System) as a tool to screen large numbers of plants for their resistance level to ToBRFV. The system simulates real-life and commercial conditions of growing tomato plants under an intense and uniform level of infection, securing that all plants are inoculated at the same age. Only after we obtain similar ToBRFV-resistance results and there are no signs of disease in plant and fruit, do we declare the variety to be ToBRFV resistant.

“The great strength of this reliable testing system is that it allows us to offer our customers something we are certain of, a product whose resilience has been tested and verified.”
