Maize KSS 7330

KSS 7330 — this is a mid-early hybrid of corn (Zea mays L.), intended for cultivation as silage and grain. The hybrid is included in the State Register for the Central Chernozem and Volga regions. The plant is tall with medium-width leaves, the leaf tip is rounded or rounded-obtuse, and the angle between the leaf blade and stem is medium. Anthocyanic coloration of the first leaf sheath varies from weak to medium, and root coloration at the stem base is weak or absent. The tassel is characterized by absence or very weak anthocyanic coloration of the spikelet scales and base, weak pollen coloration, and medium spikelet density. The main tassel axis is long, higher than the upper lateral branches, forms a small or medium angle with the lateral branches, and the primary lateral branches are slightly curved, medium in length and number. Silk and leaf sheaths have weak or absent anthocyanic coloration.

The ear is cylindrical, medium or large in length and thickness, with a medium or short peduncle. The number of rows is numerous or medium, kernel type is intermediate, closer to starchy, or dent, with yellow-orange coloration of the upper and lower parts of the kernel. Anthocyanic coloration of the ear stalk varies from weak to strong. The vegetation period is approximately 124 days, corresponding to a mid-early maturity period. Grain moisture at harvest averages around 27.9%.

The hybrid exhibits high yield: the average yield of normalized dry matter for silage in the Central Chernozem region reaches 153.3 centners per hectare, 18.2% higher than the standard, while the maximum grain yield in the region is 80.2 centners per hectare, 25.5% higher than the standard. Dry matter content averages 44.5% across the region. KSS 7330 possesses good resistance to diseases and pests: field observations indicate weak infection by ear mold, fusarium, and common smut, while stalk borer damage is assessed as moderate. This combination of characteristics makes the hybrid attractive for farmers aiming to achieve high and stable yields of both grain and silage.
