A unique PVIS

Newly born from the merger of the Israeli companies Nirit Seeds and Tomatech, the international seed company Harmoniz, preserve the legacy of leading company in the development of innovative, flavorful and virus-resistant tomato varieties, such as ToBRFV, thanks to the synergies of its excellent and experienced teams, its advanced R&D capabilities, molecular technology and breeding techniques, and its marketing channels worldwide.

On the theme of ToBRFV, Harmoniz has consolidated its innovative strength over the last 7 years, reaching a leading position today thanks to a unique plant virus inoculation system (PVIS) developed in 2015 by the company’s R&D team.

“Considering the unclear limits when defining in practice the level of resistance to ToBRFV of a variety,” says Shai Leviatov VP R&D Harmoniz “it is probably more appropriate to make explicit what allows us to declare our varieties as “resistant” to ToBRFV. At Harmoniz, when we declare our hybrids as resistant to ToBRFV, we refer to varieties that were infected at the early stages of the crop and tested several times under control and severe inoculation conditions. Under our testing conditions, these varieties preserved the ability to produce high level of commercial quality yield, without showing symptoms of disease in the plant and fruit – productivity and fruit quality are not compromised, there is good color, taste, uniform size, weight and shape”.

Thanks to this unique PVIS, Harmoniz offers wide range of commercial and pre-commercial varieties resistant to ToBRFV in various segments: the red miniplums Basoche, Dormaplum and Flor de Andalucía, the midi plum Midres, numerous specialties  like Catando, TT-768 or Tom Ruby, and a new advanced generation of resistant hybrids in all key segments, including TOV, which will be part of our commercial range in the campaign 2023-2024.

However, the ToBRFV-resistant varieties are only part of Harmoniz’s wide commercial offer for the Spanish market. In fact, the Harmoniz range includes leading varieties of segment already recognized in the market.
