Evaluation of genetic diversity of persimmon in Sheki-Zagatala economic region of Azerbaijan

Persimmon is one of the main export crops in Azerbaijan. The aim of the study was to assess the genetic diversity of persimmon in Azerbaijan. The studies were conducted in June-July 2023. Persimmon plantations in the Sheki-Zagatala economic region were studied. 30 plants were selected that differed in morphological parameters and probably belonged to different varieties. During direct field work, each plant was described by the following parameters: tree height, crown shape, length, shape and color of leaves, color and size of flowers, monoecious or dioecious plant. Genetic material was extracted according to the Doyle & Doyle (1987) protocol, purified by electrophoresis and purity tested using a spectrophotometer. As a result, it was suggested that tall persimmon trees often have a pyramidal crown shape, while short trees have a wide oval shape. Also, trees with an oval crown often have oval or heart-shaped leaves, while trees with a pyramidal crown have elliptical leaves. Genetic analysis confirmed that all 30 persimmon samples probably belong to different varieties. 25 samples had contamination. The materials collected during this work will be used in the future to establish the genetic relationship of the persimmon varieties examined in Azerbaijan.
