GEOGRAPHIC DISTRIBUTION OF PLANTS IN THE SELECTION OF AGRICULTURAL CROPS BY N.I. VAVILOV

The laws of the Republic of Uzbekistan "On Selection Achievements" and the new edition of "On Seed Production" dated February 16, 2019, the resolution of the President of the Republic of Uzbekistan dated December 29, 2015, PR-2460 "Measures for Further Reforming and Developing Agriculture in 2016-2020", the decree of the President of the Republic of Uzbekistan dated February 7, 2017, PD-4947 "On the Strategy of Actions for Further Development of the Republic of Uzbekistan," as well as other regulatory legal documents related to this activity, emphasize the great importance of selection and seed production in achieving high-quality yields from agricultural crops today. Numerous experiments are being conducted by scientists to create new varieties and primary sources. The main directions of selection work in Uzbekistan, the use of traditional methods (cross-cultivation, long-formed cross-cultivation, polyploidy, mutagenesis, heterosis) alongside biotechnology, genetic engineering, and other new methods, the significance of the variety in agriculture, and selection methods have been studied in this article.
