In the semi-arid loess plateau areas of Northwest China, water is the limiting factor for rain-fed wheat yields. Genetic advances in grain yields under rain-fed conditions have been achieved with the introduction of Rht genes. This picture, which was taken in a field of semi-arid loess plateau area in Northwest China, displays a promising autumn harvest scene resulting from introducing specific dwarf genes into current wheat cultivars. This study reviewed the mechanism involved in dwarfing genes that reduce plant height and affect root and coleoptile length, their consequent effects on grain yields and water use efficiency.
