Root system development transcribed the drought yields of chickpea genotypes. In response to drought, roots turned more prolific, thinner & penetrated deeper soils. Highest drought tolerance depended on the strength of reproductive-phase root system. RLD after 45 DAS & deep RDW before maturity & early pod-fill RSR contributed to DS. Tolerance relied on maximum water acquisition enhancing shoot biomass & partitioning.
