The arrival of affordable, high throughput DNA sequencing, coupled with improved bioinformatics and statistical analyses is bringing about major advances in the field of molecular plant breeding. Multidisciplinary breeding programs on the world's major crop plants are able to investigate genome-wide variations in DNA sequences and link them to the inheritance of highly complex traits controlled by many genes, such as hybrid vigor. Furthermore, there has been a step-change in speed and cost-effectiveness. What previously took six generations to achieve can now be done in two, delivering massive time and resource savings. This has made molecular plant breeding feasible on marginal crops including medicinal plants and crops of the developing world.
Agriculture faces demands to sustainably produce enough food for an expanding world population and to improve the nutritional quality of food crops, as well as to provide non-food crops, e.g. for the biofuels industry. The progress in molecular plant breeding can help meet these demands by;
These issues will be discussed during the session "Plant breeding today: genomics and computing advances bring speed and precision," at the Annual Meeting of the AAAS, Washington, D.C. on Saturday, February 19, 2011.
