Abstract:
The experiment was carried out at Jub Ramlah Station for Cotton Research during 2020 season according to randomized complete block design with three replications. The research aimed to evaluate fiber quality of brown cotton lines which resulted by crossing with island cotton (long-staple cotton). Results of ANOVA analysis showed high significant differences among studied characters (lint percentage, fiber length, fiber strength, fiber elongation and fiber fineness). This is a clear indication of the genetic variation among the tested genotypes. Compared to check variety (Aleppo 124), increasing rate reached %2.33 for lint percentage, %13.64 for fiber length (line 25/1), %37.05, %18.61 and %32.17 for fiber strength, fiber elongation and fiber fineness (line 25/2), respectively. The two lines 25/1 (light brown) and 25/2 (light brown) were distinguished by their high fiber quality so they must be tested in several environments to be utilized as varieties, and later used in breeding programs as well as the textile industry as naturally colored fibers.
Key words: brown cotton, upland cotton, fiber quality, intraspecific cross.
