Chickpea (Cicer arietinum L.), the second largest consumed pulse crop of the world after common bean, is grown in over 50 countries and traded across 140 countries. After several decades of slow progress, the recent years have witnessed spectacular progress in development of genetic (mapping populations) and genomic resources (structural and functional molecular markers, integrated genetic map and mapping of genes/quantitative trait loci; QTLs) in this crop. QTLs associated with traits of interest including resistance against wilt, Ascochyta blight, Botrytis grey mould and rust; tolerance against salinity and drought and agronomic traits have been identified and validated. A more than 30 genetic linkage maps available in this crop are useful resources for genetic analysis and marker assisted breeding. Genomic tools like bacterial artificial chromosome (BAC) libraries, expressed sequence tags (ESTs) and targeting induced local lesions in genome (TILLING) mutants have been developed in chickpea to facilitate the genome sequencing efforts in this crop. A major landmark in chickpea genomics has been the publication of 738 Mb draft whole genome sequence assembly of a kabuli variety, CDC Frontier. Now, chickpea is one of the most advanced grain legumes in terms of availability of genomic resources. Efforts have already begun on application of these genomics resources in chickpea improvement. This book chapter provides an update on the development of genetic and genomic resources for chickpea and their current and potential uses in chickpea improvement.
