The sunflower hybrid P64LE25 (P64LE25) is well suited for cultivation in regions with a high level of weed infestation and the presence of sycamore. This hybrid has genetic tolerance to Express herbicide or analogues, as well as double resistance to lupus (5 races + System 2). The manufacturer recommends this sunflower hybrid for cultivation in the steppe and forest-steppe zones. But, based on the score of drought resistance, which is not the maximum among Pioneer hybrids, P64LE25 seeds should not be sown in very hot areas.

Biological characteristics:
the real yield varies within the limits: minimum – 30-34 t/ha, maximum – 47-48 t/ha;
has genetic resistance to the newest breeds of lupus (System-2);
is the best in yield in its subgroup;
has a powerful stem with an evenly filled basket;
tall sunflower;
highly resistant to lodging.

Sunflower P64LE25 has good oiliness indicators. In addition, this hybrid is genetically resistant to the latest races of powdery mildew. The most suitable seeding density for sunflower under Granstar P64LE25 is within 50-60,000 plants per 1 ha.
