Table 3.
Grain yield, number of spikes per plant, number of grain per spike, 1000-grain weight and harvest index (HI) in three wheat cultivars with different root systems, grown under well-watered conditions (WW) and exposed to early season drought (ESD). ESD was induced by simulating a 25 mm rainfall after sowing in dry soil and no watering for 30 days.
