Abstract
10 new promising cotton varieties and lines were studied in a competitive variety testing. Precocious varieties and lines have been identified in which the first boxes opened on the 104th – 106th day of plant vegetation. It was found that late-ripening varieties and lines had higher yields. There was no direct correlation between the height of the crop and the density of standing plants. The best grades and lines have been identified in terms of fiber length and micronair quality. Early-ripening, high-yielding varieties Turkestan, Turan, Lines-802 and T 2/7, having the optimal combination of fiber length and quality, are recommended to be used to obtain a second crop of raw cotton (secondary crop) after harvesting early crops and crops grown under film. It is noted that the above-mentioned earlyripening cotton varieties and lines may well be adapted and recommended for cultivation in southern Kyrgyzstan and other Central Asian republics
