Abstract
This paper deals with fibre deformities in thirteen cultivars of Egyptian cotton, namely: Giza 45, Giza 70, Menoufi, Giza 68, Giza 76, and Giza 77 of the long-staple category; Giza 69, Giza 75, and Dandara of the long-medium-staple category, and Giza 66, Giza 72, and Ashmouni of the medium-staple category.
The cotton-fibre deformities were classified as major and minor according to their frequency. The major fibre deformities included thin fibre, knee, knot, small spur, and large spur, and the minor fibre deformities included forked and protuberant fibres. Differences in the number of fibre deformities between the cultivars studied, in the types of fibre deformities, and in the interaction between number and type of fibre deformities were statistically significant.
Fibre deformities occurred in between one-half and two-thirds of the neps that were formed, which confirmed their troublesome rôle in the cotton textile industry. Neps were classified into groups according to the number of fibre deformities associated with each in order to evaluate the part played by fibre deformities in neppiness.
