Abstract: 
Pakistan is among the countries badly affected by climate change. Under post-climate change scenario, water stress is becoming serious for crop production day by day. A multi-dimensional approach is needed to cope with this problem incorporating agronomic, cultural and molecular approaches. Molecular approaches are helpful in elucidating the underlying molecular mechanisms involved in stress tolerance of plants. In our research project, effort is made to identify genomic regions involved in drought tolerance of cotton. 90 SSR primers were employed to screen 94 genotypes of cotton for polymorphism. Association mapping approach was employed to identify genomic regions involved in drought stress related and yield traits of cotton (Gossypium hirsutum L.). These identified markers can be of significance for future molecular breeding efforts focused towards drought tolerance in cotton (Gossypium hirsutum L.).
