For the first time in the Republic, a special device was developed to create an artificial harmsel with different wind speeds (2; 4; 6; 8; 10 m/sec) and high temperatures (+48-50°C). A method was developed for determining resistance to garmsel and high temperature in breeding material and samples of the cotton gene pool. The research results obtained under artificial garmsel conditions were confirmed under natural garmsel conditions, on the basis of which it became possible to determine the resistance of cotton varieties to these conditions before planting and propagation in regions exposed to garmsel. The resistance of more than 30 varieties of cotton grown on large areas of Uzbekistan was studied, varieties resistant to this stress factor were isolated from them, which are recommended for genetic breeding and the creation of new varieties and lines of cotton that are resistant to garmsel and high temperatures, as well as for sowing. in areas subject to the action of harmcel.
