Maize ROSS 140 SV

ROSS 140 SV — this is an early-maturing three-line hybrid corn with a vegetative period of 90–92 days, belonging to FAO 140. The plant is of medium height, reaching 208–212 cm, with the ear forming at a height of 75–76 cm. The ear is weakly conical, medium length, with medium intensity of stem coloration. The grain is yellow, cream-colored, toothed, with a 1000-grain weight of 260–270 g and a grain yield of 80–81%. The hybrid is characterized by the absence of anthocyanin coloring of the silk and medium inflorescence structure with the main axis higher than the upper lateral branch. ROSS 140 SV stands out for its high yield and adaptability to various regions, including the Northwestern, Central, Volga-Vyatka, Middle Volga, Ural, West Siberian, and East Siberian regions. The average yield of normalized dry matter varies from 51.8 centners per hectare in the Ural region to 110.7 centners per hectare in the Central region. The grain yield in the Middle Volga region is approximately 40.1 centners per hectare. The hybrid is resistant to damage from common smut, stalk rot, and lodging, ensuring reliability during mechanized harvesting. However, the hybrid is susceptible to bacterial disease, ear fusarium, and corn stalk borer, and has resistance to southern helminthosporiosis at a level up to 9 points. These characteristics require attention when selecting protective measures and agronomic practices. ROSS 140 SV is recommended for cultivation under various climatic conditions, making it a universal solution for farmers aiming to achieve a stable and high-quality corn harvest.
