abstract: Globally, chickpea production is severely affected by salinity stress. Understanding the
genetic basis for salinity tolerance is important to develop salinity tolerant chickpeas. A recombinant
inbred line (RIL) population developed using parental lines ICCV 10 (salt-tolerant) and DCP
92-3 (salt-sensitive) was screened under field conditions to collect information on agronomy,
yield components, and stress tolerance indices. Genotyping data generated using Axiom®CicerSNP
array was used to construct a linkage map comprising 1856 SNP markers spanning a distance of
1106.3 cM across eight chickpea chromosomes. Extensive analysis of the phenotyping and genotyping
data identified 28 quantitative trait loci (QTLs) explaining up to 28.40% of the phenotypic variance in
the population. We identified QTL clusters on CaLG03 and CaLG06, each harboring major QTLs
for yield and yield component traits under salinity stress. The main-effect QTLs identified in these
two clusters were associated with key genes such as calcium-dependent protein kinases, histidine
kinases, cation proton antiporter, and WRKY and MYB transcription factors, which are known to
impart salinity stress tolerance in crop plants. Molecular markers/genes associated with these major
QTLs, after validation, will be useful to undertake marker-assisted breeding for developing better
varieties with salinity tolerance.
