О. В. Ладыженская Felted cherry is a valuable fruit crop due to its high adaptability and nutritional value of the fruit. In the territory of Russia, felted cherry is a cultivated plant. All natural populations are feral plants that entered the European part of Russia more than 150 years ago through the Primorsky Krai. The aim of the study is to assess the variability and conjugacy of fruit and leaf characters in a population of felted cherry. The subjects of the study were the wild felted cherry trees growing near the island of Patmos, Chemalsky district, Republic of Altai. Fruits and leaves were collected from 8–10-year-old plants in the first decade of July. For the research, 30 fruits and leaves each were randomly selected from the middle part of the shoots and their characteristics were estimated: fruit length (mm), fruit diameter (mm), fruit weight (g), sugar (°Bx), leaf length (mm), leaf width (mm). Fruit length and width were found to have a very low level of variability and were within 5–6%, mainly fruit length from 11.12 to 12.79 mm and fruit diameter from 10.90 to 11.39 mm. For the research, 30 fruits and leaves each were randomly selected from the middle part of the shoots and their characteristics were estimated. This population can be recommended for further research on resistance to moniliosis and possible introduction into industrial production.
