Maize SIXTUS

SIXTUS — this is a mid-season, simple hybrid of maize (Zea mays L.) intended for grain production. The plant is characterized by high cold and drought resistance, making it suitable for various climatic conditions. The vegetation period averages from 102 to 130 days, depending on the growing region. The plant is tall, reaching 220–230 cm in height, with broad leaves and a leafy stem. The leaves are straight, with a small or moderate angle between the leaf blade and stem, promoting optimal photosynthesis. The ear is medium or long, cylindrical, with a short peduncle and a high number of rows of kernels. The kernel type is intermediate, closer to dent, with yellow coloring on the upper part. The 1000-kernel mass is 340–350 g. The hybrid is resistant to stalk rot and weakly susceptible to gray leaf spot, enhancing its reliability in field conditions. The stalk borer causes moderate damage, but the hybrid maintains high productivity. The tasseling period is average, with anthocyanic coloring of the ear husk and weak to moderate intensity of silk. The ear has a medium density of florets, with the main axis positioned above the upper lateral branch, which has a moderate angle to the lateral branches. Primary lateral branches are slightly curved and medium length, ensuring good pollination and ear formation. The average grain yield in the North Caucasus region reaches 54.1 centners per hectare, 4.1% higher than the standard, and in the Lower Volga region — 46.5 centners per hectare, 4.5% exceeding standard levels. The grain moisture at harvest is about 21%, lower than standard values, facilitating subsequent drying and storage. The recommended planting density varies depending on moisture conditions: 55,000–60,000 plants per hectare in dry conditions and 65,000–70,000 plants per hectare in adequately moist zones. Due to its characteristics and adaptability, the hybrid SIXTUS is a reliable choice for obtaining stable and high grain yields.
