Declaration on World Food Security [4] on food plan action observed that, “Food security at the individual, household, national and global level exists where all people at all times have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life”. In both definitions, emphasis has been given to physical availability and economic accessibility of food to the people. The mutant varieties are often grown by farmers in their fields, and any increase of food production resulted from the cultivation of the mutant varieties could be translated into increased food security, since this should be accessible for the people in need. A detailed review on the global impact of mutation-derived varieties developed and released in major crops all over the world has been published by Ahloowalia, et al. [5]. Several papers presented in this Symposium have also elaborated the contribution of induced mutations to food security in either a particular country or a particular crop. Herewith, we present the overall role of induced mutations worldwide, by continent and country, with emphasis on those countries not already discussed in papers which are included in this book.
