Genomics, Biotechnology and Plant Breeding for the Improvement of Rice Production

Among the cereals, rice is the staple food for more than half of the global population. Rice production has decreased, while population growth rate is rapidly increasing. Thus, there is an urgent need to increase rice yield significantly to feed the increasing population. Advances in genomics and biotechnology could make rice as a model crop species with its genome completely sequenced, and using genes with important agronomic traits is the way forward to escalate the yield potential of modern rice cultivars. Of the 16 potential genes with known function for increasing yield, it is imperative to use the appropriate gene/allele-specific markers for their transfer into modern rice cultivars. Desirable breeding lines will be developed by doing a foreground and background analysis of the selected progenies. This is expected to increase the yield potential of new rice breeding lines introgressed with OsSPL14, TGW6 and GS5 genes by at least 50% over the indica rice cultivars targeted for improvement. The recently emerged genome-editing tools will be helpful for the development of superior alleles of yield-enhancing genes, for direct target gene editing in favourite rice backgrounds without cross with the donor parents, and for the elimination of linkage drag inherited from the donors. New rice cultivars with high yield potential will be developed.
