This study was conducted from early September 2003 to late April 2003 in Jubeiha, Jordan to identify chickpea genotypes tolerant to soil moisture stress at different crop growth stages. Six chickpea genotypes, i.e. 4 kabuli (FLIP-97-241, FLIP-98-107, FLIP-93-55 and FLIP-97-99) and 2 desi (DZ-10-92 and DZ-10-11), were evaluated under 4 soil moisture levels: T1, control (no stress); T2, water stress induced during vegetative growth stage; T3, water stress induced from first flower setting up to first pod setting; and T4, water stress induced from first pod setting up to physiological maturity. Thirteen agro/morphological characters were studied, i.e. days to flowering, days to maturity, seed yield per plant, harvest index, water use efficiency, 100-seed weight, number of primary branches, number of secondary branches, plant height, number of pods per plant, number of seeds per plant, number of seeds per pod, and root dry weight. Genotypes responded differently to water treatments. Under T1, FLIP-98-107 produced the highest grain yield and FLIP-93-255 gave the lowest yield. Yield was reduced by 17.5, 34.3 and 65% with moisture stress at vegetative, flowering and podding stages, respectively, compared with the yield at the field capacity. Moisture stress during flowering and podding stages severely affected seed yield and its components. However, moisture stress at the vegetative growth stage had a pronounced effect on plant height, branching and root size. The main characters affecting chickpea grain yield under moisture stress were early maturity, number of pods and seeds per plant, and harvest index. These characters could be used by breeders as selection criteria to improve crop stability in drought prone areas.
