The hybrid sweet corn GKT 211 is a mid-early variety with FAO 220, characterized by high yield and stability under various climatic conditions. The vegetation period ranges from 95 to 105 days, and the days to flowering vary from 65 to 75. The grain type is starchy, ensuring good quality and suitability for grain use. Plants reach a height of 200-220 cm, with ear attachment height of 75-110 cm, 12-16 rows per ear, and 38-42 kernels per row. The 1000-kernel weight is 280-320 g, indicating grain size and density.
The hybrid GKT 211 exhibits high stress tolerance, scoring 9 points for resistance to lodging, drought, and stress, making it a reliable choice for cultivation in areas with insufficient moisture. It has a strong stalk resistant to strong wind gusts, which helps preserve the yield during natural grain moisture loss. Additionally, the hybrid shows excellent resistance to pathogens, including corn smut, helminthosporiosis, and pests such as the corn borer. Seeds are treated with fungicides and insecticides, providing additional protection during early growth stages.
The potential yield of GKT 211 in production conditions ranges from 8.5 to 11.1 t/ha, reaching 12.1 t/ha in variety trials. The recommended planting density depends on moisture levels: 65-70 thousand plants per hectare in well-watered areas, and 60-65 thousand plants per hectare in less watered areas. Practical trials in the Zhytomyr region showed a yield of 11.06 t/ha at grain moisture of 21.3%, confirming the hybrid's high productivity and adaptability to local conditions.
