Abstract:

The problem of studying and preserving cotton biodiversity, recognized by the world community at the end of the 20th and the beginning of the 21st century, is the basis of agricultural and economic development and an essential component of food security in each country. After the independence of our country, certain successes have been achieved in the development of agriculture and the acceleration of the agrarian industry. On the basis of the implemented program activities in this direction, certain important results have been achieved, including in the creation of new varieties with high yields and resistant to stress factors. In the strategy of actions for the further development of the Republic of Uzbekistan, “the importance of rational development of agricultural production and a significant increase in the export potential of the agricultural sector” [1] is emphasized. Based on these tasks, it is important to organize scientific work to identify diagnostic signs of seeds associated with the pollution of cotton fiber and to search for early maturing cotton donors, as well as to introduce them into production.
