Seven lines of analogs with different color of leaves were created in sunflower by the backcross method of the recipient line of YuV-28B and gene donors controlling different variations in leaf color. A study of these lines at the Research Institute of Agriculture of the South-East region in 2017–2019, conducted as a competitive variety test, showed that most seed lines did not significantly differ in seed yield from the recipient line YuV-28B except for the L-4 line with olive color of the sheet, in which this indicator was lower than that of the recipient line. They were assessed analogous lines according to the phenological, morphological, crop-forming characteristics, as well as according to the quality of seeds and oil. All analogue lines had 100% shell of seeds and resistance to local races of broomrape and downy mildew. Most of the studied indicators of these lines correspond to the parameters of the source material, so they can be used in the selection of decorative sunflower.
