The Inheritance of Valuable Economic Traits Abroad and In Our Republic in The Conditions of Moderately Saline Soil and Climate of Karakalpakstan And the Infection of F3 Hybrid Families of Cotton with Wilt

Abstract

In the world, modern methods of genetics and breeding science are effectively used to create new cotton varieties and increase their sown areas. According to the United Nations, more than 1.5 billion people in the world face serious difficulties due to food shortages due to soil degradation in agricultural lands. The area of irrigated land in the republic is 4.3 million hectares, of which 44.7 percent are of varying salinity, including 31.0 percent are slightly saline, 11.9 percent are moderately saline, and 1.9 percent are highly saline. Therefore, the samples studied in this article are aimed at creating varieties that yield high and quality yields in saline soils by crossing collection samples brought from cotton origin centers with local varieties in moderately saline soil-climatic conditions of Karakalpakstan and creating initial material for selection based on the analysis of economically valuable traits of their offspring.
