Molecular breeding in cotton - Icrisat

Use of Molecular Markers in Cotton
• The first RFLPs based genetic linkage map of tetraploid
cotton was published in 1994 (Reinisch et al 1994).
• RFLPs have widely been used in cotton for genetic
diversity analysis and genome mapping.
• Reinisch et al. (1994) map was further saturated using
the same F2 (G. hirsutum x G. barbadense) population
and a detailed map was published (Rong et al. 2004).
The map consists of 2584 loci spaced at 1.75 cM in 26
linkage groups.
• Comparative map of tetraploid and its diploid
progenitors (Brubaker et al. 1999, Rong et al. 2004);
cultivated and wild tetraploid (Waghmare et al. 2005)
are now available.
