The article highlights key issues of the development of collection of varieties displaying example characteristics of sorghum bicolor and rye. It displays their applicability and value. In order to develop the varietal collections of rye and sorghum bicolor as a methodical tool of varietal examination on distinctness, uniformity and stability, a scrutiny has been given to the morphologic description, morphologic description of plant varieties systematization, as well as field examinations on the facilities of the Poltava and Zhitomir state centers for variety testing. The work undertaken has resulted into the establishment of common knowledge rye, sorghum bicolor varieties collections encompassing 330 and 30 varieties, respectively. A morphologic analyzes of common knowledge varieties enabled to single varieties displaying example characters out of the majority of grades of identification characteristics expression. In particular, for sorghum bicolor of 199 grades as set by the Text Guidelines, varieties with example characteristics were selected for 135 grades by 40 identification characters, while in rye for 81grades out of 99 grades existing by 19 identification characteristics. For each crop Lists of varieties displaying example characters were created, with example referencing to characteristic number and state of its expression indicated, namely of 16 sorghum bicolor varieties and 18 varieties of the rye. The common knowledge variety collections established could be considered as a tool for identifying local differences, i.e. in the scale of Ukraine partially embracing CIS and Europe.
