8.6.4 Genomic Resources for Elucidating Salinity Stress in Chickpea

Substantial progress on elucidation of genetics control of salinity tolerance has been reported in chickpea. However, due to its complex genetic inheritance, availability of genomic resources has enabled in underpinning salinity stress-controlling genomic regions in chickpea and thus improved our understanding of the genetic basis of salinity tolerance. First QTLs derived from JG 62 (tolerant) × ICCV 2 (sensitive) recombinant inbred lines derived mapping population-controlling seed yield under salinity stress on LG3 and LG6 were reported (Vadez et al. 2012). Subsequently, QTL analysis through SSR and SNP marker allowed unfolding of two key genomic region governing salinity stress tolerance on CaLG05 and on CaLG07 (Pushpavalli et al. 2015). The authors also unearthed several salinity stress-responsive putative candidate genes from this investigation.
