ROSINKA TARASOVSKAYA

Soft winter wheat of the Rosinka Tarasovskaya variety is a medium-early semi-dwarf variety with a vegetation period ranging from 232 to 285 days. This variety is distinguished by its lodging resistance and high winter hardiness, ensuring reliable plant development in Rostov Oblast and other regions of the North Caucasus and Lower Volga districts. Plant height ranges from 56 to 95 cm, the ear is cylindrical with medium density and a length of up to 9 cm, and the mass of 1000 grains is 34-48 g. The variety belongs to the erythrosum type and is characterized by a strong waxy bloom on the flag leaf and ear, as well as the absence or weak anthocyanin pigmentation of the glumes.

Rosinka Tarasovskaya demonstrates high yield, with average indicators in Rostov Oblast reaching 30.5-32.1 c/ha, which exceeds the standards of the variety Donskaya bezostaya by 3.1-3.5 c/ha. The maximum yield registered in the region amounted to 96.2-105 c/ha. The variety is characterized by intensive growth and the ability to effectively assimilate mineral substances due to a low stable stem, which contributes to the formation of large and high-quality ears. It is adapted to a wide range of predecessors, including non-fallow crops, which expands the possibilities for its cultivation.

The grain quality of the Rosinka Tarasovskaya variety is highly valued in milling and baking production. The grain contains 13.3-14.7% protein and 23.9-33.4% gluten, has good dough rheological properties with alveograph readings of 350-370 units and a volumetric bread yield of about 960 cm³. The variety shows resistance to powdery mildew, snow mold, septoria, and brown rust, although it is susceptible to solid head smut. Thanks to the combination of high yield, quality characteristics, and resistance to major diseases, Rosinka Tarasovskaya is a promising choice for intensive cultivation of winter wheat in southern regions of Russia.
