Wheat is the most widely grown and consumed cereal in the world and its demand is expected to grow due to increasing population, change in food habits in favour of wheat and nutritional requirements. Despite adverse effects of biotic and abiotic stresses, India harvested all time high wheat production of 85.93 million tons from 29.5 million hectare during 2010-11. To address the challenges of plateauing yield, anticipated threats and researchable issues, an International Group Meeting was organized during February 9-12, 2011. In this international event, renowned researchers of different disciplines representing wheat growing countries deliberated on various issues. The information encompasses various researchable areas, possible impact of climate change and future strategies to enhance wheat production on sustainable basis. This book will be very useful for the wheat researchers, students and policy makers for ensuring food and nutritional security at global level.
