The variety is classified as corn (Zea mays L.). Official documentation confirms its registration in state plant variety registers; however, detailed characteristics, including exact plant height, disease resistance, or a detailed description of product quality, are absent from open sources.
In some official materials, the maturity group for the Tetraktys variety is indicated as corresponding to FAO 400 code. Additional data on breeding origin or specialization for grain or silage use are not provided in available publications.
