PR39R86

Technological architecture of the PR39R86 hybrid

This hybrid from Pioneer s.a. is a breeding solution with an FAO of 90–1240, focused on versatile use — both for grain and silage. A key feature of this hybrid lies in its grain structure: the flint-type composition ensures a high density of starch compounds. In practice, this means increased resistance to field pests and less susceptibility to damage when stored under field conditions.

Phytosanitary profile and genetic protection

The agronomic efficiency of PR39R86 is supported by strong genetic resistance to key corn field pathogens. Breeders have focused on mitigating the risks of loose and common smut, diseases capable of reducing yields by 20–30% in epidemic years. High tolerance to these infections minimizes fungicide costs and ensures the preservation of ear quality.

Vegetation period and adaptability

The ripening period of 120–140 days places this hybrid in the medium-late group, requiring strict adherence to planting dates to achieve the required heat unit accumulation. The simple hybrid type guarantees crop uniformity and simultaneous ripening, which is critical for mechanical harvesting. The dense grain structure and balanced vegetative mass development make it a reliable tool for farms aiming to produce high-energy silage with high dry matter content, as well as commercial grain with excellent test weight indicators.
