With HREZ, producers embattled by the threat of ToBRFV for years have a chance to return to preferred planting dates and regular harvest cycles, while anticipating more consistent quality and potentially higher yields. In turn retailers can expect better supply planning and more consistency in product quality. HREZ is a label that enables the tomato industry to look forward with confidence.

In 2016 one plant showed remarkable promise, which had that one small difference that would make an enormous impact. Now we are proud to present our exclusive collection of High Resistance tomato varieties by Enza Zaden (HREZ) developed to combat the ToBRFV outbreak. ToBRFV has been destroying entire crops and threatening the global tomato industry since 2014. There has been a significant decline in tomato production yields, a rise in production costs and a threat to tomato quality at every level of the supply chain due to this highly contagious virus. Our HREZ collection is a game-changer, helping prevent the spread of ToBRFV and revolutionising the tomato industry.

With over 1000 ha of High Resistance by Enza Zaden (HREZ) varieties successfully cultivated around the world, tomato growers are looking forward to a brighter future. Today, Enza Zaden offers several varieties with High Resistance to Tomato Brown Rugose Fruit Virus (ToBRFV). The varieties are available in all significant tomato types, and do not compromise on taste, yield or quality. The trust and dedication of our valued grower, shipper and retailer partners has contributed greatly to the success and fast adoption rate of HREZ varieties in all major tomato production regions.

During the last eight years the tomato industry has faced significant challenges due to the spread of the ToBRFV virus. This industry is worth over $190 billion annually and plays a crucial role in our food supply chain. Phytosanitary protocols are being enhanced, labour is being increased and crops are being rotated more frequently to combat the virus. These measures have not been enough to eradicate the virus and have increased industry costs. In addition, unmarketable fruit reduced yields and forced the industry to switch to suboptimal planting dates and short harvest cycles. Infection rates are still rising in over 30 countries despite these measures. Tomato varieties with High Resistance benefit not only your operation but the entire industry. It is a small step that can make an enormous difference in combating the spread of ToBRFV.

Grafting on a rootstock may have negative effects on the characteristics and resistance of the HREZ tomato varieties. There are certain mutations and there may emerge further mutations of ToBRFV for which HREZ tomato varieties do not offer High Resistance or for which resistance has not yet been established. Performance of the HREZ tomato varieties may differ due to multiple factors beyond Enza Zaden’ control, including but not limited to, environmental and agronomic factors. Products at times carry seed borne diseases or have lower resistance to plant diseases which may not be apparent to Enza Zaden. In addition, inclusion of disease resistance traits in newly developed varieties may have other growth impacts including but not limited to growth disorders and hypersensitive reactions to environmental conditions.
