Recently, the well-known breeder, senior research fellow of the Volyn Institute of Agro-Industrial Production, Iryna Ivanivna Maister, received a certificate of authorship issued by the State Service for the Protection of Rights to Plant Varieties for the winter rye variety she created — Iryna. After two years of State Variety Testing, the Iryna variety was entered into the State Register of Varieties of Ukraine starting from 2004 and recommended for cultivation in the Polissia and Forest-Steppe zones. The Iryna variety belongs to the diploid species, is characterized by high productivity, yields good harvests at the level of 50–55 centners per hectare both on sod-podzolic sandy and sandy-loam soils, as well as on gray podzolized soils and shallow chernozems, which indicates its high ecological plasticity. It belongs to the group of highly winter-hardy varieties. Unlike other varieties, it does not require chemical protection, as it is resistant to diseases and pests. It is also resistant to lodging and shattering, which creates convenience during harvesting. The maximum yield was obtained at the Kryzhopil variety testing plot in Vinnytsia Oblast — 89.8 centners, in 2003 at the Verkhivnia variety testing plot in Rivne Oblast — 68.0, and at the Peremyshliany variety testing plot in Lviv Oblast — 54.4 centners per hectare. The baking qualities of the variety are good. Protein content is 11.0–11.4 percent. Grain test weight is 720–750 g/l. The mass of 1000 grains is 35.0–39.7 grams. In terms of technological qualities, the variety belongs to the intensive type, is characterized by high tillering, responds positively to the application of mineral fertilizers, ensuring a high grain yield. The cultivation technology for the winter rye Iryna was developed by the Volyn Institute of AIP. We hope that managers and specialists of agricultural enterprises, farmers, and rural residents will pay close attention to introducing the new winter rye variety Iryna on their fields. All the more so since there is an opportunity to purchase high-quality seed of the variety firsthand, namely, at the Volyn Institute of Agro-Industrial Production, located in the urban-type settlement of Rokyni, as well as to receive highly qualified consultations on cultivation technology.
