Among the abiotic stresses, drought is a serious limiting factor that reduces rice production and yield stability in rainfed ecosystems. Conventional breeding for drought resistance is slow in attaining progress due to poor understanding of genetic control of drought resistance. Molecular markers help in identification of quantitative trait loci (QTLs) associated with drought resistance traits and their indirect selection using marker assisted selection. But QTL mapping requires genotyping of large mapping progenies demanding time and labour. Bulked segregant analysis (BSA) serves as an alternative approach for rapid identification of markers associated with drought resistance
traits.
