M 55 22

Technological potential of the M 55 22 hybrid

The M 55 22 sunflower hybrid, developed by Agrosemena, is an intensive, simple hybrid designed for stable yields in farming systems requiring high phytosanitary standards. The key technical advantage of this model is its genetic adaptation to imidazolinone-based herbicides (Clearfield system), allowing for the effective control of a full spectrum of weeds and broomrape throughout the vegetative cycle.

Phytopathological profile and morphology

The hybrid's resistance to pathogens relies on built-in defense mechanisms against primary diseases: downy mildew, phomopsis, and phoma. This minimizes the risk of leaf surface loss and ensures robust head filling. The plant’s dimensions (170–180 cm height) facilitate efficient harvesting with standard combine equipment, minimizing crop loss. With a vegetation period of 100–110 days, it is classified as a mid-early hybrid, optimal for regions with limited active temperature windows.

Oil content economics

The oil content in the seeds ranges from 45% to 50%, a result of high metabolic efficiency within the plant. These attributes, combined with tolerance to the Euro-Lightning herbicide, make M 55 22 a high-tech solution for farms aiming to reduce labor costs and minimize the stress impact of weeds on commercial crops.
