Chromosome substitution lines of the wheat variety ‘Cappelle Desprez’ into ‘Chinese Spring’ were tested for drought tolerance in growth chambers in the Martonvásár phytotron. Three different moisture regimes were created: E1, fully irrigated control; E2, mid‐season water stress (preanthesis); and E3, terminal water‐stress during grain filling. Data were analysed to estimate the chromosomal location of the genes controlling relative water‐content (RWC), relative water‐loss (RWL), drought‐susceptibility index (DSI) and phenotypic stability in each substitution line. Simultaneous consideration indicated that most of the genes controlling these characters are located on chromosomes 1A, 5A, 7A,4B, 5B, 1D, 3D and 5D.
