Abstract

The present research was carried out to determine water-stress tolerance of chickpea genotypes (Diyar 95, Arda, Inci, Seckin, Hasanbey) grown under (winter planting), different water conditions [no water-stress (I-100); strong water-stress (10)] in the years 2016 and 2017. Variance analyses revealed significant differences between the genotypes (P < 0.01). As the average of two years, the greatest yield was obtained from no water-stress x genotype interaction (I(100)xHasanbey) with 2681.31 kg ha(-1), the lowest yield was obtained from strong water stress x genotype interaction (I(0)xSeckin) with 1702.17 kg ha(-1). Again as the average of two years, the greatest chlorophyll content was obtained from no water-stress x genotype interaction (I(100)xHasanbey) with 47.78 spad, the lowest value was obtained from strong water stress x genotype interaction (l(0)xSeckin) with 36.81 spad. The greatest crop water stress index was obtained from strong water stress x genotype interaction (I(0)xSeckin) with 0.56, the lowest value was obtained from no water-stress x genotype interaction (I(100)xHasanbey) with 0.18. The Hasanbey genotype with optimum water use efficiency and prominent with crop water stress index and chlorophyll content both in no water stress and strong water stress treatments was identified as water stress-resistant and the genotype was considered to have reliable characteristics potentially to be used in further water stress-resistance studies.
