RECOVERY OF REPRESENTATIVES OF THE GENUS AEGILOPS L. FROM SEED IN FERGANA VALLEY

In the course of the research, the geographical distribution of representatives of the Aegilops L. genus throughout the Fergana Valley, the seed reserve in the cenopopulations, and the regeneration from the seed were determined. A GIS map and species composition were determined based on the data obtained throughout the Fergana Valley. Among the species studied is Aegilops crassa Boiss. We observed that the ecological range of Fergana Valley is somewhat limited. This species was found only in the Khojabad district of Andijan region, Imam ota hillsides (940032'47.66"N, 72036'21.8"E, at an altitude of 807 m above sea level, at a latitude of 2010 south-west). The number of bushes was small, 19 per 1 . In recent years, the genus Aegilops L. has been the most intensively studied group of grasses, especially since its close relationship with wheat cultivars was discovered. In particular, it helps to improve complex traits such as abiotic tolerance for drought and heat, in increasing the productivity of wheat varieties. Therefore, studying the influence of climatic conditions on the change of the biological characteristics of the species of the genus, a their geographical distribution in the Ferghana Valley is of great scientific and practical importance.
