Résumé
Climate change is altering the amount and patterns of rainfall, affecting wheat production in dryland agricultural regions. Availability of soil water is critical for wheat to maintain yield stability. The form and function of root system is critical for accessing soil water to minimize water deficit. This study examined the role of wheat root system size in conferring drought tolerance to early season drought and terminal drought. This study concludes that the role of root system size and its interdependence with shoot traits and phenology deserves more attention by wheat breeders especially under the climate change/variability scenario.
