Eleven parental cotton genotypes (Gossypium barbadense L.) and their 28F1hybrids were canvassed by Principal Components and Linkage Cluster analyses to identify the major characters which account for the variation in yield contributing traits. Analysis of variance revealed highly significant differences for genotypes, crosses, parents for all the studied traits.  Parents vs. crosses were significant for most traits indicating the heterotic response. The first principal component contributed 41.9 %to the total variability and was mainly attributed to plant height, boll weight, seed cotton yield/plant, number of fruiting branches/plant, lint yield /plant, boll number and seed index. The second PCs contributed 16.7 % to the total variability and were mainly due to fiber fineness, length and uniformity ratio and showed positive loadings with most characters. The PC3 and PC4 contributed 9.1 % and 7.9 % of the total variability and were mainly attributed to pressely index, earliness index, vegetative branches and days to flowering. The 11cotton parental genotypes were grouped into four major clusters based on dissimilarity among them and sixteen contributed characters. The female parents (testers) Suvin, (Giza 88xOkre leaf), (Giza 85xOkre leaf) and 24202 were grouped into two wide clusters. The parental genotypes Giza 93 and (Giza 81xAustraly12) formed two wide clusters from the other parents and having wide dissimilarity coefficients compared with other parents.  The 39 genotypes, 11 original parents and 28 F₁ crosses, were grouped into 13 major clusters relative to dissimilarity among them.
