Principe

Genetic architecture of the "Principe" hybrid

The agronomic potential of the "Principe" maize hybrid, developed by the French breeding center (Av Du Capitaine N Tchorere, Airaines), is based on the classic genetics of a simple hybrid. This crossing scheme ensures a maximum heterosis effect, resulting in crop uniformity and predictable response to agronomic conditions. Grain productivity is complemented by a high starch content of 72%, making the crop highly valuable for both commercial crop production and the livestock sector for the production of high-energy silage.

Phytosanitary barrier

The biological defense of the hybrid is designed to counter specific threats to intensive cropping. Breeders have prioritized complex resistance to key pathogens:

• Common smut: Genetically embedded resistance minimizes the risk of yield loss under high humidity during critical development stages.
• Fusarium and stem smut: Using this hybrid allows for a reduction in fungicide application, as the plant possesses inherent mechanisms to suppress infection pressure.

Technical parameters

The vegetation period of 120–140 days classifies "Principe" as a medium-late maturity hybrid. The dent-type grain provides an optimal balance between moisture dry-down rate and thousand-kernel weight. When planning the sowing campaign, it is important to note that high starch accumulation energy requires strict adherence to harvest dates to reach target grain moisture. Utilizing this hybrid for silage enables the production of stable, high-digestibility feed due to the kernel structure, which is ideally suited for processing into high-quality fodder mass.
