ASSESMENT OF FIBER QUALITY OF SOME UPLAND COTTON GENOTYPES IN NORTH CENTRAL NIGERIA

Abstract

This study was conducted to evaluate the fiber quality traits of selected cotton genotypes cultivated in North Central Nigeria, with the aim of identifying superior lines for enhanced textile performance. Key fiber parameters assessed included spinability index, fiber strength, length uniformity, fineness, maturity, and upper half mean length (UHML). Results revealed that Samcot 11 exhibited the highest spinability index (152.25), length uniformity (86.58%), and fiber strength (29.08 kNmkg⁻¹), indicating its potential for high-quality yarn production. Samcot 10 recorded the highest fiber fineness (4.38), while Samcot 12 had the lowest fiber maturity value (0.85%). All other genotypes displayed relatively uniform maturity values (0.86%) with no significant differences. However, UHML values across all genotypes were below 21 mm, reflecting generally short fiber lengths. The findings highlight Samcot 11 as the most promising genotype in terms of overall fiber quality, suitable for further development and utilization in cotton improvement programs in the region. K
