Product Highlight

Choosing the right tomato rootstock is an important decision. The rootstock influences plant vigor, disease resistance, yield potential, and how well your scion variety performs over a long crop cycle. Here's a straightforward comparison of the main rootstock varieties available from Paramount Seeds. For a broader introduction to rootstock selection, see our rootstock selection guide, and our step-by-step grafting guide for growers new to grafting. Shop Tomato Rootstock → At a Glance Variety Vigor Best For Key Strength Maxifort F1 High Long crops, weak/generative scions High vigor Multifort F1 High Soil crops with Fusarium race 3 pressure Fusarium 3 + nematode resistance Estamino F1 High, Generative Growers managing vegetative crops Balanced, generative effect Kaiser F1 Balanced Long cycles, larger fruit size Early, high production DR0141TX F1 High Long crops, versatile scions Highest yield potential in De Ruiter range Variety Profiles Maxifort F1 Maxifort is one of the most vigorous rootstocks commercially available and has long been a go-to for high-wire, long-cycle greenhouse production. It excels on weak or generative scion varieties, boosting plant endurance and yield potential. Suitable for both soil and rockwool systems. Read our Maxifort F1 product spotlight for full details. Note: pelleted seed materials are not suitable for organic production. Best for: Long crops, rockwool and soil, generative or weak scions. Multifort F1 Multifort matches Maxifort in vigor but adds a critical disease package: Fusarium race 3 resistance combined with nematode resistance. This makes it the preferred choice for soil-grown crops where Fusarium 3 is a known risk. Using a strong rootstock like Multifort can extend plant life and increase average fruit weight. See our guide to understanding HR and IR disease resistance for help reading resistance codes. Best for: Soil crops, Fusarium race 3 pressure, long cycles. Estamino F1 Estamino takes a different approach — it's vigorous but with a distinctly generative effect on the grafted scion. Rather than pushing excessive vegetative growth, it promotes a well-balanced plant with steady, consistent production from start to finish. Ideal for growers who struggle to control overly vegetative crops. Broad disease resistance including TSWV and Fusarium 0-2. Best for: Growers managing vegetative growth, long cycles, soil and substrate crops. Kaiser F1 Kaiser offers a balanced, controlled vigor — strong and generative without being excessive. It promotes early, high production and tends to produce larger fruit size, making it well suited to market segments where fruit grade matters. Good plant balance throughout the crop cycle. Best for: Long cycles, larger fruit size, balanced vigor requirements. DR0141TX F1 DR0141TX is De Ruiter's highest yield potential rootstock and is particularly valued for its versatility — it works well with both vegetative and generative scion types. It increases vigor and endurance, making it especially useful for long crops. See our detailed Maxifort vs. DR0141TX comparison to decide which is right for your operation. Seed is untreated, primed, and pelleted. Note: may not be suitable for organic production — verify with your certifier. Best for: Long crops, maximum yield potential, versatile scion compatibility. How to Choose Growing in soil with disease pressure? Multifort (Fusarium 3/nematodes) is your best option. Growing in rockwool or substrate on a long cycle? Maxifort or DR0141TX for maximum yield; Kaiser for balanced vigor and fruit size. Struggling with vegetative, hard-to-control plants? Estamino's generative effect will help bring balance. Need organic-compatible options? Check with your certifier — several pelleted rootstocks use non-organic pellet materials. New to grafting?

Shop Tomato Rootstock → Maxifort F1 — The Vigor Standard Maxifort is one of the most vigorous rootstocks available and has been the industry benchmark for long-crop tomato production. It excels in both soil and rockwool systems and is particularly well-suited for weak or generative scions that need a strong root system to reach their yield potential. If you're running a demanding long-season crop and want a rootstock with a proven track record, Maxifort is the reliable choice. Read our Maxifort F1 spotlight for full details. Best for: Long crops, generative or weak scions, soil and rockwool systems.Note: Pelleted seed is not suitable for certified organic production.

It increases vigor and endurance across a wide range of scion types — both vegetative and generative — and is especially valuable for long-season crops where sustained performance matters. It also carries a strong disease resistance package: HR to Fusarium (For), Plasmopara (Pl), and ToMV strains 0–2, with IR to root-knot nematodes (Ma, Mi, Mj). Best for: Maximum yield potential, long crops, nematode pressure, broad scion compatibility.Note: Seed is untreated, primed, and pelleted. Verify organic suitability with your certifier.
