RP 556 is a high-yielding corn variety with high disease resistance and adaptability to various soil-climatic conditions. It is characterized by stable yield and drought tolerance, making it a reliable choice for agricultural cultivation. The variety is suitable for both monoculture and minimum tillage systems, ensuring high grain quality.
This variety belongs to the mid-maturing group and exhibits good water release during maturation, facilitating efficient harvest. RP 556 demonstrates high resistance to lodging and diseases such as rust and head fusarium, significantly reducing the risk of yield losses. The recommended planting density at harvest is 70-85 thousand plants per hectare, optimizing productivity and grain quality.
According to research conducted at the All-Russian Research Institute of Corn, RP 556 showed high general and specific combining ability, indicating its genetic value and potential for breeding work. This variety stands out among white-seeded lines for its yield and resistance, confirming its prospects for wide application in different regions with varying climatic conditions.
