Abstract
This research was to study the genetic divergence evaluation of  
some cottoncollection (Gossypium barbadens L.) to select the most suitable genotypes as well as to investigate the importance of evaluate characters, by using multivariate analysis. Based on these data, the first three factors which accounted for 83% of the total variance are important. Factor I included lint%, lint index, lint cotton yield and fiber fineness and its accounted 43% of the total variance. Only fiber length had negative loading indicates the direction of the relationship between the factor and variable. Factor II included seed index, fiber strength and fiber length accounted 25%. Factor III included boll weight and fiber strength and its accounted 14% of the total variance. The most divergent genotypes were Australian 12 and Giza 45 × SeaIsland at genetic distance (23.88%). In contrast, the level of similarity was high (95% and more) between 84% from extra long genotypes and between 88% from long stable genotypes.
