Variety description

10 August 2026

The variety belongs to the 'augmented supersweet' category; the cobs are 20 cm long and contain 16–18 rows of glossy yellow-white kernels. The plant reaches a height of 1.8–2 meters and is protected by dense dark green husks.

The vegetation period is about 74 days. Sowing requires warmed soil above 15–16°C due to low seed germination energy. To maintain taste qualities, spatial isolation from other types of corn is necessary. The variety is intended for fresh market cultivation, and a tendency to lodging has been noted.
