The paper analyzes the results of the technical examination for the new cultivar of Dactylis glomerata L., created at Agricultural Research and Development Station Lovrin, SCDA Lovrin, examination that was carried out with the purpose of enrolling the new cultivar in the The Official Catalog of cultivated plant varieties from Romania. Two genotypes of Dactylis glomerata L., the synthetic LVDG1 cultivar as a tester and the homologated Magda cultivar as control were used as biological material. The tests were carried out in the 2021-2023 period, on the territories of six administrative-territorial units, distributed in different geographical areas of our country: Șimleu Silvanei, Dej, Satu Mare, Sibiu, Negrești și Rădăuți. The tests followed the main quantitative characteristics (production of dry matter and fresh fodder) but also features such as spring growth vigour, regeneration capacity, drought resistance, resistance to falling and resistance to disease. From the tests carried out in the ISTIS network, it follows that the LVDG1 cultivar met the criteria for homologation, being approved in 2024 with the final name of Theodor. The maximum dry matter yields for the new cultivar were on average 21.5 t/ha D.M., with a suitable quality in nutritional elements, good regeneration capacity, and, good resistance to climatic factors, falling and disease. Dactylis glomerata L. is a perennial grass that also grows spontaneously in the meadows of Romania. It is an important species in the composition of simple and complex feed mixtures, therefore it is of great importance in breeding and conservation programmes.References
