Hybrid sweet corn Boyán 277 MV belongs to the medium-early varieties with a vegetation period from 105 to 128 days and belongs to the maturity group FAO 310. The grain is dent-type, yellow, with 1000 grain mass of 290–315 g. Plants reach a height of 230–255 cm, with ear attachment height of 110–125 cm. The average number of kernels per row varies from 38 to 45, and rows per ear from 14 to 18. The hybrid is intended for grain production and is characterized by high yield, reaching 11–13.5 t/ha under production conditions and up to 14.3 t/ha on variety trial plots. Boyán 277 MV is characterized by high stress tolerance (8 points), excellent lodging resistance (9 points), drought tolerance (8 points), and cold tolerance (9 points). The hybrid has high plasticity and rapid early growth, enabling it to successfully adapt to various soil-climatic conditions, including weak and sandy soils. Due to rapid moisture release, drying costs for grain are reduced. Plants have strong stalks that maintain stability even in overripe conditions, contributing to yield retention. Recommended planting density is 65–70 thousand plants per hectare in well-watered zones and 60–65 thousand plants per hectare under water-stressed conditions. The hybrid responds well to early planting, allowing avoidance of drought periods during flowering. Seeds are treated with fungicides and insecticides, providing protection against rust, head smut, stalk and root rot. Due to its agronomic qualities and resistance to adverse factors, Boyán 277 MV is a reliable choice for obtaining stable and high yields of sweet corn.
