Table 4 Mean values for maximum root length (rooting depth; cm), maximum root length:shoot length ratio (unitless) and total root length (cm) of the six highest (top) and six lowest (bottom) ranked wheat–alien chromosome lines along with the CS check under irrigation (control) and drought stress (water withheld for 58 d) (Experiment 2)

From: Alien chromosome segment from Aegilops speltoides and Dasypyrum villosum increases drought tolerance in wheat via profuse and deep root system
