The hybrid sweet corn MAS 431B is a mid-season simple hybrid with phenomenal yield potential, intended for grain production. It features a dent kernel type and a stalk type of 'stey green'. Plant height and ear attachment are at a medium level, with kernel rows ranging from 32 to 38 per ear and rows per ear varying from 16 to 18. The 1000-seed weight is in the range of 320–340 grams, indicating high seed density and quality. The package contains 50,000 seeds, facilitating ease of sowing and harvest planning. The hybrid MAS 431B is characterized by high plasticity and good adaptability to various growing conditions, confirmed by its resistance to drought, lodging, and rapid water loss. The initial growth energy of the hybrid is very high, enabling it to develop successfully at early sowing and rapidly accumulate vegetative mass. Recommended growing zones include the Polissia, Forest Steppe, and Steppe of Ukraine, where the hybrid demonstrates stable yield performance. To achieve optimal grain maturity, an accumulated active temperature of approximately 1850 degrees is required, and for the vegetative period from germination to flowering, approximately 970 degrees. MAS 431B exhibits high resistance to major corn diseases such as gray leaf spot, stalk and ear fusarium, and southern rust, significantly reducing the risk of yield losses. Recommended plant density at harvest varies depending on the moisture zone: in adequately moist zones — 70–85 thousand plants per hectare, in insufficiently moist zones — 60–70 thousand. The hybrid's yield potential exceeds 160 centners per hectare, making it an attractive choice for farmers seeking high productivity and reliable crops.
