ToBRFV-Resistant Tomato Varieties from Paramount Seeds
Tomato Brown Rugose Fruit Virus (ToBRFV) remains one of the most serious threats to commercial greenhouse tomato production. With no chemical cure and rapid spread through mechanical contact, genetic resistance is the most reliable line of defense. Paramount Seeds carries a curated lineup of DeRuiter® varieties with validated multi-gene intermediate resistance to ToBRFV — across beefsteak and truss types — so you can protect crop quality without compromising yield or fruit uniformity.
| Variety | Type | Fruit Weight | Key Strength |
|---|---|---|---|
| Riboski (DRTH5066) | Beefsteak | 290–340 g | Extra-large, ribbed, high °Brix, 10+ day shelf life |
| DRTH5075 | Beefsteak | 265–310 g | Touché-conversion, smooth uniform fruits, summer stability |
| Grandice Res (DRTH1060) | Truss (TOV) | 170–195 g | Grandice-conversion, FULLRED, jointless truss, PM resistance |
| Serenity (DRTH1053) | Truss (TOV) | 190–220 g | High marketable %, FULLRED, PM + TSWV resistance |
| Tomagino Seram (E15C.43080) | Cherry on the Vine | 18–22 g | HR ToBRFV, crunchy, tasteful, easy generative plant |

DRTH5075 — F1 Beefsteak Tomato
A Touché-conversion developed by DeRuiter®, DRTH5075 brings the proven fruit quality and yield potential of its predecessor together with validated multi-gene ToBRFV resistance. Ideal for growers transitioning from Touché who need a rugose-resistant beefsteak without sacrificing uniformity.
- Fruit weight: 265–310 grams
- Smooth, round, shiny fruits with little to no ribbing
- Compact, balanced plant habit for high-wire systems
- Strong summer production stability
Disease Resistance:

IR: ToBRFV (validated) / On
Truss (TOV) Varieties
Grandice Res (DRTH1060) — F1 Truss Tomato
For growers who valued the high yield potential and glossy FULLRED fruits of the original Grandice, Grandice Res is the ToBRFV-resistant conversion. It adds multi-gene IR to ToBRFV and anticipated IR to Powdery mildew, while maintaining the compact plant habit and large, uniform fruits the variety is known for.
- Fruit weight: 170–195 grams
- Jointless truss with uniform, glossy fruits
- FULLRED for excellent external and internal color
- Good shelf life and summer fruit size consistency
Disease Resistance:
HR: ToMV:0-2 / ToTV / Fol:1,2 / For / Pf:A-E / Sbl / Sl / Ss / Va:1 / Vd:1
IR: ToBRFV (validated) / On / Ma / Mi / Mj
Serenity (DRTH1053) — F1 Truss Tomato
Serenity is a jointless, large-truss tomato developed for high-tech glasshouse growers. It combines multi-gene ToBRFV resistance with IR to Powdery mildew and a vigorous, balanced plant that supports high yield potential. Serenity has demonstrated a high percentage of marketable fruit and good speed of maturation.
- Fruit weight: 190–220 grams
- Jointless truss with good shape
- FULLRED color — excellent internal and external
- High marketable fruit percentage and good shelf life
Disease Resistance:
HR: ToMV:0-2 / ToTV / Fol:1,2 / For / Pf:A-E / Sbl / Sl / Ss
IR: ToBRFV / TSWV:0 / On
Cherry Varieties
Tomagino Seram (E15C.43080) — F1 Cherry Tomato on the Vine
Tomagino Seram is a large cherry-on-the-vine variety from Enza Zaden with high resistance (HR) to ToBRFV — a step above intermediate resistance. It produces tasteful, crunchy fruits in a nice cluster presentation, and its generative plant behavior makes it easy to manage in the greenhouse. Excellent crack resistance rounds out a strong commercial package.
- Fruit weight: 18–22 grams
- Crunchy texture with excellent crack resistance
- Generative, easy-to-manage plant habit
- Seed is untreated as standard
Disease Resistance:
HR: ToMV:0-2 / ToBRFV / ToANV / Va:0 / Vd:0 / Fol:0 / For
IR: Un
Why ToBRFV Resistance Matters
ToBRFV spreads rapidly through mechanical contact — tools, hands, clothing — and has no chemical treatment. Once present in a greenhouse, it can devastate fruit quality and marketability across an entire crop. Varieties with validated intermediate resistance provide a meaningful genetic barrier, reducing the risk of severe crop loss and supporting continuity of production even in infected environments.

Resistance Disclaimer: Disease resistance is not the same as immunity. Resistant varieties are bred to limit the growth and development of a specified pathogen under normal disease pressure, but they are not immune. Under very high pest or disease pressure, resistant plants may still show symptoms or sustain some damage. High resistance (HR) and intermediate resistance (IR) ratings are defined by breeder specifications and do not guarantee complete protection in all growing environments. Always implement sound sanitation and integrated pest management practices alongside the use of resistant varieties.
