Numerous species have been acclimatized and bred at VRDS Buzau, among which special results have recently been obtained for Sideritis scardica, also known as Mursalski chai. After completing the acclimatization stage, the valuable genotypes were subjected to intensive breeding works, obtaining six genotypes with distinct phenotypic expressiveness. During the vegetation period, biometric, phenological and biochemical observations were performed, applying the same crop technology for all studied genotypes. The results showed visible differences in terms of phenotypic expressiveness of the main characters. Regarding the weight of the inflorescence and the number of inflorescence/plant, G1 ranks first with an average value of floral mass of 790 g/plant, and G5 has the highest leaf mass value with an average value of 1198 g/plant, while G2 has the most intense fragrance on all vegetative aerial parts. All six genotypes showed genetic stability and uniformity in descent. In 2019, G1 genotype was patented and registered in the Official Catalog of Crop plant varieties from Romania under the name 'Domnesc’ cultivar and used in this study as control variant.
