N2  - Cereal crops are vital for meeting the food, feed and nutritional demands of the world. However, long-term production growth of cereals could be severely affected by the changing climate, which is already exacerbating existing challenges such as drought and heat stresses, insect pests and diseases, and soil degradation, especially in the tropics. While adaptation to climate change would require convergence of appropriate technologies, policies and institutional innovations, the focus of this chapter is on some of the promising genomic tools and strategies that can enhance time- and cost-effectiveness of breeding for climate-resilient cereals. For this, we use maize as a case study, considering the availability of genomic resources, the significance of maize as the number one cereal crop in the world at present in terms of total area and production, the vulnerability of sub-Saharan Africa (where maize is the most important staple food crop) and South Asia (where maize plays a significant role as food and feed) to the changing climates. CIMMYT?s experiences and initiatives with regard to designing and implementing modern breeding strategies for developing climate-resilient maize varieties, including high-density genotyping, whole genome resequencing, high-throughput and precise phenotyping, doubled haploids (DH), genomics-assisted breeding (e.g., genome-wide association studies, breeder-ready marker development, rapid-cycle genomic selection, marker-assisted recurrent selection), and crop modeling are particularly highlighted here. The key challenges to the international scientific community are (a) to generate high-quality phenotypic data in breeding programs, and integrating the same with modern tools and technologies for accelerated development of climate-resilient germplasm; (b) to better understand the effects of climate change on diversity of cropping systems in different regions; and (c) to effectively monitor the patterns of change both temporally and spatially, coupled with appropriate policies and actions at the farm level
