Cotton is an economic plant of world importance. It is the world's leading textile fiber crop and it is also a source of secondary products such as oil, live-stock feed (cotton seed cake) and cellulose (Anderson 1999 and Frelichowski et al., 2006). Assessment of genetic markers and diversity form an integral part of any successful breeding program. Morphological features are indications of the genotype but are represented by only a few loci because there are not a large enough number of characters available. Moreover, they can also be affected by environmental factors and growth practices. To overcome the limitations associated with morphological markers, various biochemical and molecular marker techniques have come up in recent years. Biochemical markers such as isozymes have been used to study the genetic distances and estimate the level of genetic variability of cotton varieties and accessions (Wendel et al., 1989; Percy and Wendel, 1990; Abdel-Tawab et al., 1990 & 1993; Melchinger et al., 1991; Wendel et al., 1992; Sukumar and Allan, 1998; Farooq et al., 1999). However, isozyme analysis has certain limitations due to the availability of a limited number of marker loci, a general lack of polymorphism for these loci in elite breeding materials, and the chance of variability in banding patterns being due to plant development (Tanksley et al., 1989). Protein markers have also been used to identify different cotton species, varieties and lines (Khan, 1991; Goyal, 1993; Renata et al., 2004; Murtaza et al., 2005; Yunuskhanov et al., 2007; Kurbanbaev et al., 2008).
