Afficher plus [+] Moins [-]Chickpea incurs heavy yield losses due to terminal heat and drought as it is largely grown under rainfed restricted irrigated conditions on residual soil moisture. The narrow genetic base among cultivated chickpea accessions is limiting genetic improvement of chickpea through breeding efforts. Exploring the extent of natural variation among cultivated chickpea accessions for drought tolerance is important to develop pre-breeding and breeding strategies for chickpea. Thirty sevenlandracesrepresenting fivecountries and fourteen provinces obtained from ICARDA evaluated for theirRelative Water Content (RWC) and Membrane Stability Index (MSI) which are established physiological parameters for drought tolerance.Theanalysis intoRWC has indicated wide variability in the landraces for drought tolerance.RWC followed a similar pattern to MSI. The genotypes IG5856(Jordan) and IG5904 (Iraq) were having higher MSI and higher RWC indicating theirsuitability as donors for terminal drought tolerance
