Seed Quality Knowledge Center
High-quality seeds mean high performance for youStriving for excellence and high quality is central to our people and processes. Quality is in our DNA. It’s in our core. This means when you plant our seeds, you can start the season with the confidence of high quality and high performance.
Every successful crop starts below the surface.
Growers need rootstocks they can rely on season after season. As soil-borne disease pressure, water stress, climate variability, and production demands continue to increase, rootstock selection has become a strategic agronomic tool that helps maintain vegetative–generative balance and support consistent crop performance throughout the growing cycle.
De Ruiter constantly helps growers and plant raisers build stronger, healthier, and more productive crops through rootstock innovation. Our rootstocks are designed to deliver the vigor, endurance, and reliability needed to support high-performing tomato production in this increasingly challenging growing environment.
Whether you are managing disease pressure, climate stress or long crop cycles, the right rootstock provides the foundation for lasting crop performance.
Why Grafting Tomato Plants?
Growing conditions bring new challenges every season.
Increasing disease pressure, climate variability, water challenges, and the need for reliable yields mean growers need crops that can perform consistently under pressure. Grafting combines the best characteristics of two plants:
- A high-performing scion that produces the desired fruit
- A vigorous rootstock that supports growth and plant health
The result is a stronger plant that can make better use of water and nutrients, maintain crop balance, and continue performing when conditions become challenging.
Benefits of grafting
Grafting can support:
- Stronger root development
- Better plant establishment
- Vigorous crop growth along the entire crop cycle
- Enhanced stress tolerance, like temperature variations
- Better water and nutrient uptake
- Resistance to certain soil-borne diseases
- Greater crop consistency and quality
- Increased yield and plant potential
How to choose the right Tomato Rootstock?
Outstanding rootstock performance starts with the qualities that matter most to growers. At De Ruiter, we believe that these can be grouped into three key pillars:
1. Powerful Vigor & Endurance
Strong roots help plants reach their potential and support crop resilience.
Our rootstocks are bred to support vigorous growth, maintain crop balance, and keep plants productive throughout the season. This translates into stronger plant development, stable fruit quality, and better crop resilience under stressful conditions.
2. The Right Portfolio for Every Growing Strategy
There is no one-size-fits-all solution.
Growing system, climate, scion choice, disease pressure, cultivation medium, and production goals all influence which rootstock is the best fit. That's why De Ruiter offers one of the broadest rootstock portfolios on the market.
More than just a portfolio: a set of strategic management tools for every growing strategy, matching the diverse requirements of modern tomato production.
A full range of solutions across different vigor levels, endurance profiles, and soil-borne disease-resistance packages, helping growers make informed rootstock selections for their specific situation.
Our portfolio includes best-sellers like:
NEW! DRTX6695
Protection with resistance to Nematodes
Maxifort
The rootstock with endurance. Our most used and popular rootstock
DR0141TX
The most vigorous rootstock with the highest production potential in De Ruiter portfolio
Multifort
Optimal balance in various conditions
Equifort
A generative rootstock with excellent endurance.
… and many more varieties designed to meet growers’ needs across all growing environments worldwide
3. Rooted in Experience
For more than six decades, De Ruiter has been shaping the rootstock market with value-driven innovation through breeding expertise, scientific research, and close collaboration with growers worldwide.
From pioneering rootstock varieties such as Beaufort and Maxifort to today's newest solutions, our innovations are developed to solve real cultivation challenges and tested under commercial growing conditions before reaching growers.
Our commitment extends beyond breeding and delivering high-quality seeds; it also includes providing technical support and field guidance to help growers and advisors. Technical guidance is provided in good faith based on available information and is not a substitute for professional agronomic advice tailored to specific conditions. Our support helps growers and advisors:
· Evaluate rootstock performance under their specific growing conditions.
· Optimize crop management throughout the production cycle.
· Select the right rootstock as part of a complete agronomic strategy.
· Optimize crop vigor, resilience and yield potential
What role does Rootstock play in ToBRFV management?
Tomato Brown Rugose Fruit Virus (ToBRFV) continues to challenge tomato production around the world.
As growers search for solutions, it is important to understand what rootstocks can — and cannot — do.
Scion Resistance as a Key Driver of ToBRFV Protection
External independent scientific studies & internal research consistently show that resistance expressed in the scion is the primary determinant of ToBRFV performance in a grafted plant. Rootstock resistance alone provides limited additional protection.
Research also demonstrates that:
· Root-mediated infection is highly inefficient.
· Root-to-scion movement of the virus is extremely limited. Mechanical transmission through handling of the above-ground plant parts (i.e. the scion), remains the dominant infection pathway.Hygiene and sanitation remain essential components of any ToBRFV management strategy.

Why Rootstock Matters in a ToBRFV Environment?
Because strong plants perform better under stressful conditions.
A vigorous root system supports healthy, balanced growth by improving water and nutrient uptake, reducing stress, and helping maintain productivity throughout the season, even under challenging conditions.
In a ToBRFV environment, rootstock contributes through vigor and endurance—helping growers preserve yield potential, fruit quality, and crop longevity while other above-ground protection layers address the disease itself.
Managing ToBRFV Through the Disease Triangle Approach
At De Ruiter, we recommend a comprehensive disease management strategy built around three pillars:
Host
Resistant scions and strong genetics
Pathogen
Hygiene, sanitation, early detection and virus containment
Environment
Vigorous rootstocks and optimized crop management towards powerful crop
Together, these elements form the so-called Disease Triangle, a well-known framework in plant pathology, that can help growers manage risk and build more resilient production systems.
Find the Right Rootstock for Your Crop
Every crop. Every challenge. Every growing strategy. Choosing a rootstock is a strategic decision.
In today’s increasingly challenging growing conditions, the question is not just which rootstock to use, but how to optimize crop performance for each production system and growing scenario. Whether your priority is maximizing yield, balancing vegetative growth, extending crop cycles, or managing disease pressure, De Ruiter offers a rootstock solution designed to help you achieve reliable results.
Plan smart. Plant strong!
Frequently asked questions about ToBRFV
A vigorous root system can help maximize yield potential and maintain fruit quality.
Rootstock supports plant strength and endurance, while resistant scions remain the primary protection against ToBRFV.
No. Different crops, climates, and cultivation strategies require different rootstock solutions.
More than 60 years of rootstock expertise, proven performance, and a portfolio designed to meet the diverse requirements of growers worldwide.
In response to requests from growers seeking a broader diseases package, Bayer is expanding De Ruiter portfolio with rootstocks that include resistance to ToBRFV. As a pioneer in tomato rootstocks, this development reflects Bayer’s commitment to meet growers’ needs. This does not change our science-based evidence and recommendations: to effectively manage ToBRFV, the optimal strategy remains combining resistant scions with vigorous, resilient rootstocks to ensure strong, productive crops under challenging conditions.
