De Ruiter, a vegetable seed brand of Bayer, introduced Solstic, its first Roma tomato variety with multi-gene intermediate resistance to Tomato Brown Rugose Fruit Virus (ToBRFV). The variety is designed for high-tech greenhouse production and supports both lit and unlit cycles.

Why it matters

Tomato Brown Rugose Fruit Virus threatens tomato crops, and resistant varieties give growers a way to manage that risk within greenhouse production. Solstic adds a resistant option to De Ruiter's Roma lineup for producers seeking consistent yields.

Solstic's fruit averages 90 to 110 grams and is uniform and oval-shaped, according to De Ruiter's product description. The extraction does not include independent trial data verifying the intermediate resistance to Tomato Brown Rugose Fruit Virus.

Timeline

  1. Solstic was introduced on November 4, 2026.

Seasonal Patterns

Solstic extends ToBRFV resistance breeding from existing tomato lines into the Roma type, which is widely grown for processing and fresh greenhouse production. Its introduction follows the wider industry push to develop resistant varieties as ToBRFV spread across tomato-growing regions worldwide.

For growers, a variety with intermediate ToBRFV resistance can reduce the production risk posed by the virus in greenhouse operations. Growers wanting to evaluate Solstic can request a private appointment at De Ruiter demonstration houses in Leamington, Canada, or the Netherlands.

The takeaway

Resistant tomato varieties like Solstic give greenhouse growers a practical tool against Tomato Brown Rugose Fruit Virus. Growers evaluating new varieties can arrange on-site trials at De Ruiter facilities before committing to production.
