BRO 54 A

Sunflower BRO 54 A is a highly adaptive hybrid with resistance to sunflower rust, a significant advantage for protecting the crop from the parasitic plant. Resistance to sunflower rust is indicated by Latin letters, each corresponding to a specific race of the parasite. Hybrid BRO 54 A offers protection against races A to G, ensuring reliable defense against most known biotypes. Such resistance helps prevent significant yield losses, which can reach from 0.9 to 4.5 centners per hectare on infested fields.

In addition to resistance to sunflower rust, this hybrid is characterized by high resistance to various diseases, including phoma, phoma psidium, verticillium, downy mildew, sclerotinia, as well as white, dry, and black mold. It also demonstrates high drought resistance, making it suitable for cultivation in various climatic conditions, including the Central and Southern Steppe and Forest-Steppe. The hybrid is adapted to extensive cultivation technologies and is resistant to the herbicide tribenuron-methyl, which facilitates crop care.

Sunflower BRO 54 A is distinguished by stable high yield, reaching up to 54 centners per hectare, and high oil content in seeds — about 53%. Good head fullness, resistance to lodging and shattering make this hybrid attractive to agricultural producers striving to obtain a high-quality and high yield. It is recommended to update the seed material annually to avoid the risk of infection by new races of sunflower rust, which will maintain the effectiveness of protection and high yield levels.
