Abstract

This collection of studies underscores the significance of molecular markers in enhancing rice breeding programs. Research details the application of various marker systems, including SSRs, SNPs, InDels, ISSRs, and retrotransposon-based markers, for genetic diversity assessment, trait dissection, and marker-assisted selection. Key applications include developing varieties tolerant to drought, salinity, and submergence, as well as improving resistance to diseases like bacterial blight. Advanced techniques like GWAS and genomic selection are highlighted for their efficacy in accelerating genetic gain and improving selection accuracy for complex traits such as grain yield. The findings collectively advocate for the strategic integration of molecular markers with conventional breeding to foster sustainable rice production and enhance global food security.
