Abstract
The present investigation was carried out on six Egyptian cotton varieties namely; Giza 45, Giza 76, Giza 70 (Extra - long staple ) , Giza 81, Giza 75 and Dendara ( Long - staple ) to study the relative contribution of grade components to grade index and the relationship between trash cottont %, percent reflectance (Rd%), degree of yellowness ( +b), microniare reading, grade index and yarn physical properties i. e, yarn irregularity (c, v. %), thin places , thick places , nep count and yarn appearance grade. The results showed that , (1) Rd% was the most contributer to lint grade in all varieties except in Giza 45 and Giza 70 varieties where the best contributer was +b and trash content % respectivly . (2) The relationship between yarn physical properties and each of lint grade index and grade components were highly significant in all the studied varieties.
