Variety description

10 August 2026

The Ludo hybrid is mentioned in scientific and agronomic publications as an object of plant physiology research conducted by the French National Institute for Agricultural Research. The main focus of work with it was the analysis of root system architecture, metabolism, and responses to environmental factors.

Open sources lack information on commercial characteristics such as maturity group, plant height, or disease resistance indicators. The hybrid is not represented in seed catalogs for the mass consumer and appeared primarily in experimental studies of the 1990s and 2000s.
