Response of shoot ionic (Na+/K+) distribution on yield and agro-physiological traits in chickpea (Cicer arietinum L.) recombinant inbred lines population under salinity

The current study reports the effects of salinity on yield and its component traits along with physiological phenotyping to identify salt tolerant recombinant inbred lines (RILs) from set of 232 F8 RILs (ICCV 10 x DCP 92-3) population. High salt stress showed reduction in yield, relative water and chlorophyll content. Results showed, RILs genotypes 193, 157 and ICCV 10 were displaying maximum tolerance. Further lower Na+ and higher K+ accumulation in shoot along with significant increase in leaf proline content in tolerant genotypes with less leakage of ions under stress was key for tolerance under salt stress.
