Abstract:
Rice is very important food crop for Asian countries. Among different biotic, abiotic stresses, drought is a major limiting factor for rice crop production. Plants are most susceptible to drought stress at the reproductive stage. Drastic grain yield reduction occurs if drought stress coincides with reproductive stage. So drought resistance at reproductive stage is very important trait (Yue et al 2006).The development of molecular techniques for genetic analysis has led to a great increase in our knowledge of cereal genetics and our understanding of the structure and behavior of cereal genomes. These molecular techniques, such as molecular markers, have been used to monitor DNA sequence variation in and among the species and create new sources of genetic variation by introducing new and favorable traits from land races and related grass species.
