Abstract: Using traditional methods and methodologies, plant breeding has been very effective in producing improved varieties. Nowadays, the availability of genomic tools and resources leads to a new plant breeding revolution as they promote the study of the genotype and its relationship with the phenotype, particularly for complex traits. Genomics (coined in 1986 by Tom Roderick) is an interdisciplinary research field that focuses on the study of any organism's genome. Genomics field revolves around gene analysis and gene working. It is generally classified as structural genomics, functional genomics, comparative genomics, epigenomics, translational genomics and pharmacogenomics. Functional genomics links the organism’s genome to its function and phenotype. It could be further subdivided into proteomics, transcriptomics and metabolomics and could be studied by reverse genomic techniques like RNAi and mutagenesis. Genomics or decoding the plant genome sequence using high throughput techniques will allow scientific community to access agronomically important genes and will speed up the breeding programs for the development of superior varieties with higher yield and stress tolerance.
