Rapeseed DK Exima

Technical Potential of the DK Exima Hybrid

Monsanto's breeding program for winter oilseed rape focuses on plant architecture management. DK Exima is a simple linear hybrid where intensive branching acts as the primary productivity driver. This structural trait allows the crop to optimize the distribution of photoassimilates during pod filling, which is essential for achieving the stated yield potential of 60–70 dt/ha.

Agronomic Management and Seeding Density

The genotype of this hybrid is optimized for various planting densities. The recommended seeding rate ranges from 400,000 to 500,000 seeds per hectare, allowing agronomists to adjust to specific regional moisture levels and planting windows. This plasticity is rooted in the plant's ability to adapt the number of side branches based on competition for space.

Phytosanitary Resistance

Phoma stem canker (Phoma lingam) remains a significant challenge in oilseed rape production. DK Exima incorporates specific traits for increased tolerance to this pathogen. This engineering solution reduces the risk of premature stem cracking and yield loss—critical for farms with intensive crop rotations where the infection pressure of Phoma is typically high. The combination of morphological robustness and genetic protection makes this hybrid a reliable choice for achieving high yields in intensive production systems.
