The hybrid belongs to the mid-season group with a vegetation period of 80 to 105 days after transplanting. The heads have a light green color and are characterized by high density, while being less compact in structure than classic varieties and possessing thinner, more tender leaves.
At a planting density of 28 thousand plants per 1 hectare, the weight of a single head exceeds 5 kg. The hybrid is distinguished by high resistance to thrips and major field fungal diseases, as well as good adaptability to various climatic conditions, including drought.
Due to the structure and succulence of the leaves, the variety is in demand in cooking for preparing cabbage rolls, rolls, as well as for fermenting whole heads and processing. The produce is suitable for fresh consumption.
