Variety description

10 August 2026

The variety is being studied as a nematophagous crop or a non-host plant for root-knot nematodes (Meloidogyne spp.). Scientific interest is focused on studying the composition of metabolites, particularly thiophenes, and their role in suppressing pests.

Available publications lack morphological descriptions of the plant, such as bush height or maturity group. Research is aimed at a comparative analysis of the degree of nematode penetration into the roots of this variety.
