Table 7 Mean values for seed set percentage, individual seed weight (mg seed−1) and seed yield (g plant− 1) of six highest (top) and six lowest (bottom) ranked wheat–alien chromosome lines along with CS check under irrigation (control) and drought stress (water withheld for 16 d) (Experiment 3)

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