Variety description

10 August 2026

The Ludelle variety was used as a control or test sample in scientific experiments aimed at analyzing crop physiology. In particular, it featured in studies on nitrogen accumulation curves, evapotranspiration, and the improvement of fertilizer application methods based on the nitrogen nutrition index.

A specialized description of morphological traits or economic characteristics is absent from public registries. The variety is regarded in literature as an object of classical research rather than as a modern commercial sample.
