Developing new varieties and improving Elaeagnus orientalis L. through selective breeding in Uzbekistan

Abstract

Throughout ancient times, plants have played a crucial role in human life. They started off as a main source of food, and as agriculture developed, they turned into an essential supply of genetic material for growing plants. Increasing plant production and product quality via breeding and cultivation is a major part of our civilisation today. The Elaeagnus orientalis tree stands out among the many fruit trees that have been extensively grown in our nation for a long time. From ancient times, plants have played a significant role in human life. At first, they were mainly used for food, and with the development of agriculture, they became a crucial source of plant genetic material for cultivation. During the experimental observation, a total of 87 promising oriental Elaeagnus orientalis trees were identified in various regions of Uzbekistan, including Tashkent, Karakalpakstan and Khorezm, Fergana, Syrdarya, Samarkand, Kashkadarya, and Surkhandarya. Samarkand -7 varieties; clones had low growth indicators at the beginning of the growing season, but at the end of the growing season, they had an average of 132.9±5.9 cm, the Samarkand-7 variety showed a high result in terms of the number of bruised cuttings by 81%.
