Table 3 Range, mean and least significant difference (LSD) for plant height (cm), maximum root length (rooting depth; cm), maximum root length:shoot length ratio (unitless), total root length (cm), root diameter (mm), root volume (cm3), tiller number (plant− 1) and stem dry weight (g plant− 1) of wheat–alien chromosome lines 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
