Technological fiber quality of new cotton lines

Abstract

The development of new varieties of cotton is very important for increasing the yield of cotton in the Republic of Uzbekistan. An urgent task is the creation of new, early ripening, high-yielding, high-quality cotton varieties that meet the requirements of world standards. On the fields of the Namangan Scientific Experimental Station, 9 new cotton lines in competitive varietal testing were studied. According to the results of the analysis obtained when testing the quality of the fiber, at competitive variety testing of cotton lines, fiber microneur was evaluated, its strength, length, uniformity, short fiber index, relative elongation, weediness, number of defects (Cnt). As a result of the analyzes, it was revealed that the highest results in all technological indicators of the fiber were obtained from lines 112,116 and 148. These lines in terms of fiber quality fully meet all the requirements of light industry. At present, research at a scientific experimental station to bring these lines to varieties and to ensure the production of high-quality fiber varieties continues.
