PHYTOCENOTIC FEATURES, GENETIC RESOURCES AND SELECTION OF FORMS Buckthorn Buckthorn (HIPPOPHAE RHAMNOIDES L.) IN UZBEKISTAN

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

“…The weight of fruits, seeds, and flesh was accurately measured using an electronic scale with a precision of 0.01 grams. The promising forms of Elaeagnus orientalis were evaluated based on their biomorphological productivity and biochemical and tasting results and were submitted to the Agricultural Crops Varieties Testing Center of the Republic of Uzbekistan [1][2][3][4][5]8]. After successfully passing the tests, these Elaeagnus orientalis varieties were registered with the state, and the required documents were submitted to the Intellectual Property Agency under the Ministry of Justice of the Republic of Uzbekistan.…”

“…In the summer, high temperatures and low soil moisture negatively affect the tree's condition, causing leaves to shrink and adopt a boat-like, twisted shape to protect themselves from water scarcity. This leads to reduced water evaporation, branch damage, fewer fruit buds, and easily crushed fruits [1][2][3][4][7][8][9][10].…”

“…Similarly, the adaptive flexibility of the tree is assessed visually and scored on a scale of 1 to 5 based on health, annual branch growth, leaf development, and signs of damage from frost, pests, and diseases. Heterosporosis disease severity is evaluated using a point system, with a score of 0 indicating no damage and a score of 5 indicating severe damage, where the tree is about to die [1].…”

“…Plants have been an integral part of human life since ancient times. Initially, they served as a primary source of sustenance, and with the advent of agriculture, they became a vital source of genetic material for plant cultivation [1][2][3][4]. Today, our civilization is closely linked with the cultivation and breeding of plants to increase their productivity and improve product quality.…”

“…Instead, local residents grow ordinary forms in various oases, but these forms often do not possess valuable economic traits. Therefore, large-scale cultivation of Elaeagnus orientalis is necessary, which involves selecting promising forms, improving and selecting from existing assortments [1][2][3]7]. This requires extensive research on the gene pool of the oriental Elaeagnus orientalis, the identification of new forms, and a comprehensive assessment of their valuable economic and biological characteristics.…”
