Interpretive Summary:

Technical Abstract: The twentieth century witnessed tremendous progress towards meeting food security for the current population of 7.8 billion. However, in the 21st century we collectively face many challenges such as alleviating hunger, a nutritious diet for the poorer populations, quality food for all, and the sustainable management of natural resources such as land and water. Additionally, natural climatic changes leading to extreme weather patterns and human-influenced changes world over, which include the ever-growing population, have been blamed for adversely affecting the agricultural environment, causing an enormous strain on the food production chain. In particular, the field crops that feed the world and sustain human health are being hampered by the increasing incidences of diverse environmental stresses (abiotic and biotic) that affect crop yields. This warrants urgent action from the plant scientific community to devise rational strategies and minimize the impact of these stresses on crop yields. In this chapter, authors have provided an update on the approaches, especially the genomic methods, that are useful to researchers to improve field crops under diverse abiotic environmental stresses.
