This paper reviews the characteristics identified for improved drought resistance based on two frameworks ('drought resistance' and 'yield component'), and evaluates the potential of these characteristics to improve breeding efficiency in grain legumes. The first framework (the 'drought resistance framework') identifies the specific physiological and biochemical characteristics that lead to improved yields in drought-prone environments through drought escape, dehydration postponement and dehydration tolerance. The 'yield component framework' considers yield variation in terms of characteristics affecting water use, water use efficiency and harvest index. Future prospects are mentioned.
