Sunflower ALEX 2101

Alex 2101 sunflower is a medium-early simple hybrid of new linoleic genetics, characterized by high yield and adaptability to various climatic conditions. The vegetation period ranges from 109 to 114 days, allowing effective use in regions with moderate climates. Plants reach a height of 160 to 200 cm, ensuring good productivity and resistance to lodging. Oil content in seeds varies between 47–52%, making this hybrid attractive for high-quality oil production.

The hybrid exhibits high resistance to major sunflower diseases, including sclerotinia, frogeye leaf spot, powdery mildew, gray mold, and downy mildew, as well as to new races of the pathogen A–G. Additionally, it is resistant to herbicides containing tribenuron-methyl (SU), facilitating weed control and reducing protection costs. Alex 2101 sunflower also demonstrates high drought and heat tolerance, enabling cultivation under limited water conditions without significant yield loss.

For successful cultivation, seed sowing is recommended at soil temperatures of +10...+12°C, ensuring uniform and rapid germination. Optimal soils are chernozems, dark chestnut, and chestnut soils with clay, loamy, or sandy loam texture and slightly acidic, neutral, or slightly alkaline reaction. Plant density prior to harvest should be 50–60 thousand per hectare, promoting maximum yield potential, reaching 4.8–6.0 t/ha. Due to its characteristics and resistance, hybrid Alex 2101 is a reliable choice for farmers seeking high and stable sunflower yields.
