Purpose. Methods of creating high-yielding stevia varieties with a high content of diterpenic glycosides and their ecological evaluation in different regions of growing. Methods. Polyploidy, hybridization, induced morphogenesis, experimental mutagenesis in vitro. Results. As a result of breeding work at the Institute of Bioenergy Crops and Sugar Beet, three new generations of stevia were created, namely Halyna, Maryna and Kateryna. According to the results of ecological tests carried out in the Central Forest-Steppe (Kyiv region) and North Steppe (Kherson region), their productivity (yield of green and dry leaves, content of stevioside) was considerably higher, as compared to the reference (variety Berehynia). Conclusions. In order to obtain the yield of green leaves at the level of 30–37 t/ha, and dry leaves of 2.80–3.60 t/ha with the content of stevioside within 14.5–21.8%, it is recommended to plant varieties of the new generations, namely: Halyna, Maryna and Kateryna
