In: Alexandria Science Exchange Journal 2017.v.38(1)Summary: Cotton plant belongs to the genus Gossypium which is considered as the first important economic crop in Egypt. The present study aims to characterize five Egyptian cotton varieties (Giza(G) 92;Giza(G) 93; Giza(G)86; Giza(G)87and Giza(G)88) at biochemical and molecular level. Using ISSR; SSR and RAPD-PCR analyses, a total of 159 polymorphic fragments were recorded with similarity of 40; 23.5 and 38%, respectively, for the five varieties. The Phylogenetic relationships of the five Egyptian cotton varieties based on DNA molecular data (RAPD + ISSR + SSR) indicated two groups with 56% similarity; the first group had (G88); However, G93 and G86 with homology percentage of 81%, and both of them in relation to G87 variety with approximately 65.5% similarity.
