PR39B93

Genetic Potential and Ear Structure

The PR39B93 hybrid from Pioneer s.a. is a selection solution focused on intensive grain production. A key feature of this simple hybrid is the combination of flint-dent grain type with a high starch content (70%), making it highly demanded in feed production and the processing industry.

Biological Cycle and Agronomic Parameters

A maturity period of 100–110 days allows for effective planning of the harvest campaign, avoiding excessive moisture accumulation. The FAO index in the 90–1240 range emphasizes the hybrid's adaptability to various temperature zones. The simple hybrid type ensures high crop uniformity, which is critical for grain harvester calibration and obtaining commodity grain of a homogeneous fraction.

Technological Phytopathogen Control

Pioneer s.a. breeding includes built-in resistance mechanisms to key fungal diseases, particularly corn smut. The dense stalk structure and genetic stability allow the plant to maintain its architecture during the physiological maturity phase, minimizing lodging losses even during late harvesting.

• High starch yield (70%) to increase the energy value of the grain.
• Flint-dent grain type provides an optimal balance between density and moisture release speed.
• Simple genetic structure increases yield predictability in various agro-climatic conditions.
