Kiy 250 SV

Genetic Architecture of the Kiy 250 SV Hybrid

The three-way hybrid type of Kiy 250 SV from "Rasava" represents a deliberate focus on plasticity and field stability. Utilizing three lines in the parentage scheme allows for an effective cross between high yield potential and robust environmental adaptability. In practical terms, this results in uniform emergence and an increased capability of the crops to withstand stress factors during critical growth stages.

Phytosanitary Potential and Resistance

A key engineering decision in this hybrid is the strong genetic backbone designed to combat common maize pathogens. Breeding efforts prioritized the reinforcement of cell walls, directly impacting resistance to infection:

• Root rots: A dense root zone structure hinders pathogen mycelium penetration.
• Common smut: A high immunological threshold prevents cob deformation and loss of productivity.
• Stalk rots: Stem rigidity is achieved through an optimal mechanical tissue ratio, minimizing lodging risks even during delayed harvesting.

Agrotechnological Parameters

With an FAO rating of 90–1240 and a vegetation period of 120–140 days, Kiy 250 SV is positioned as a versatile solution for intensive farming. The dent-type grain structure ensures excellent moisture release during maturation, which is crucial for reducing energy costs during post-harvest processing. Due to these combined characteristics, the hybrid shows high nutrient conversion not only into dry grain but also into high-quality silage, maintaining a balanced sugar and fiber content in vegetative organs until the time of harvest.
