A set of 180 chickpea (Cicer arietinum L.) genotypes was evaluated under rainfed drought prone situation in north India. Same set was also evaluated under irrigated situation created artificially by supplementing the crop grown under rainfed conditions with two irrigations one at the time of flower initiation and another at pod set. Data on yield and its related traits, drought tolerance efficiency and incidence of wilt caused by Fusarium oxysporum f.sp. ciceris were recorded. Drought tolerance efficiency had significant and positive association with seed yield per plant, leaf area, plant height, secondary branches per plant, pods per plant, seeds per pod, biological yield per plant, harvest index and 100-seed weight under both drought and normal water conditions. On the other hand, days to 50 per cent flowering and days to maturity were negatively correlated with seed yield per plant under drought conditions indicating that early maturity was a desirable trait in chickpea breeding for drought stress. Drought enhanced wilt incidence in chickpea indicating a positive interaction between these two stresses and suggesting that drought in wilt pathogen infested areas would be more devastating. Based on yield performance and wilt resistance, nine genotypes, three desi (ICC-8521, ICC-1915 and L-328) and six kabuli (ICC- 14203, ICC- 14199, ICC-10755, ICC-10885, ICC-11819 and ICC-11284) were found promising for cultivation under drought conditions where as four kabuli types (ICC- 14203, ICC- 14199, ICC-11819 and ICC-11284) were suitable for cultivation under well watered conditions.
