Abstract

After drought salinity is the major abiotic stress that severely affects agricultural productivity globally. Chickpea(Cicer arietinum L.) is the important grain legume which suffers approximately 8-10% of total global yield loss due to salinity. Screening for salt stress is difficult and traits that correlate salinity tolerance are least understood. The present study was carried out at ICAR-IARI, New Delhi 2017-18, deals with the important morphological and physiological traits like RWC (Relative water content), EL (Electrolyte Leakage), Na/K (sodium and potassium ratio) to characterize the salt tolerant genotypes under hydroponic condition which is a quick and easy method to screen large number of chickpea genotypes at initial stage under salt stress condition. Genotypes showing high RWC, low EL and Na/K ratio were tolerant like ICCV 10, JG 11, JG 62 and CSG-8962 whereas genotypes like ICC4958 and Pusa362 fall under moderately tolerant genotypes and DCP 93-3, Pusa 256, Phule G5 and SBD 377 were classified as susceptible genotypes. This study also attempts to understand the candidate genes responsible for salt-stress related pathways in chickpea genotypes based on sequence similarity approach exploiting known salt-stress responsive genes from model crops or other crop species.
