Tomato Rootstock Varieties Compared: Which One Is Right for Your Greenhouse?

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.

At a Glance

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. 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.

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. 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

A few key questions to guide your decision:

• 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.
