Abstract
The materials used in the present study included the 2 long staple varieties Giza 75 and Giza 80 as well as the 2 extra-long staple Giza 76 and Giza 77. A range of lint cotton grades from Fully Fair to Good/Fully Good, in increments of either 1/4 or 1/2 of a grade, was used from each variety. The values of colour index and grade factor were used as numerical indications of cotton grade in order to secure reliability and accuracy of cotton quality specification. The results obtained indicated that colour index and lint grade were found to correlate strongly and positively in the white coloured cotton varieties Giza 75 and Giza 76, while this correlation was not significant in the creamy coloured varieties Giza 77 and Giza 80. On the other hand, grade factor correlated positively and significantly with lint grade in all studied varieties. In conclusion, grade factor appeared to be an elaborate and credible numerical means that could be used satisfactorily to define and specify the grade and quality of cotton without much reliance on classer's grade, which is mostly subjected to a great deal of contravention and inconsistency, since it is entirely qualitative.
