Variety description

10 August 2026

The hybrid was used in scientific experiments studying irrigation regimes, the influence of the soil nematode Meloidogyne javanica on plant development, and comparative biomass productivity. Information regarding origin, parental lines, and commercial purpose is absent from the sources.

In comparative trials with low soil moisture content, the hybrid showed higher leaf transpiration intensity and water potential compared to some other samples. When evaluating dry matter accumulation and bioenergetic potential, the variety was inferior to other participants in the studies.
