Approximately 25 % of global agricultural land is utilized for wheat cultivation, making wheat the largest food crop worldwide in terms of area. Wheat is the second most produced cereal crop after Maize with more than 650 million tons produced every year. Wheat productivity is increasing at less than 1 percent annually, while the annual productivity must increase at 2 % annually to meet the global demand. The potential of increasing arable land is limited; hence future increases in wheat production must be achieved by enhancing the productivity per unit area. Increasing grain yield, yield stability, resistance/tolerance to biotic and abiotic stresses, and end-use quality characteristics are among the most important wheat breeding goals. The Green Revolution wheat varieties performed well in terms of responsiveness to fertilizer application and water-use efficiency. But now there is not a lot more water to spare, and fertilizer usage in some places has already passed saturation point, so a new Green Revolution will have to make even more efficient use of existing resources. Efficient phenotyping techniques are essential to develop new wheat varieties with higher yield potential, tolerate high temperatures and improved water-use efficiency or drought tolerance due to climate change and the dwindling supply of irrigation water. This book chapter describes various phenotyping techniques being used in national and international wheat breeding programs.
