Maize RHR 1702

RHR 1702 is a corn hybrid with early- and mid-season maturity depending on the growing region. It is distinguished by high yield and versatility in use. The plant is tall, reaching 230-250 cm in height, with a medium-length, cylindrical ear positioned 90-100 cm above the base. The grain has an intermediate type, closer to a flinty texture, with an orange coloration at the top and bottom, and a 1000-grain weight of approximately 230 g. The vegetation period varies from 80 to 114 days depending on the region, allowing flexible adaptation to different climatic conditions.

The hybrid exhibits good resistance to southern helminthosporiosis and moderate resistance to stalk rot and gray leaf spot, but is susceptible to ear bacterial blight and Fusarium ear rot. It also shows a medium level of damage from the corn borer. The grain loses moisture quickly upon maturation, facilitating harvest and reducing storage losses. The average dry matter content in the grain ranges from 23.5% to 35.8% depending on the region, contributing to the production of high-quality raw material.

RHR 1702 demonstrates high yield of normalized dry matter across various regions, including the Northwestern, Central Volga, West Siberian, and Far Eastern regions. In the Northwestern region, the yield reaches 112.2 c/ha, in the Central Volga region — 104.6 c/ha, in the West Siberian region — 70.8 c/ha, and in the Far Eastern region — 116.7 c/ha. These figures exceed regional standards, making the hybrid attractive for agricultural production. Due to its agronomic characteristics and adaptability, RHR 1702 is suitable for cultivation in various climatic zones to obtain high-quality grain.
