Chickpea (Cicer arietinum) is the second most widely grown legume crop after soybean, accounting for a substantial proportion of human dietary nitrogen intake and playing a crucial role in food security in developing countries. We report the ∼738-Mb draft whole genome shotgun sequence of CDC Frontier, a kabuli chickpea variety, which contains an estimated 28,269 genes. Resequencing and analysis of 90 cultivated and wild genotypes from ten countries identifies targets of both breeding-associated genetic sweeps and breeding-associated balancing selection. Candidate genes for disease resistance and agronomic traits are highlighted, including traits that distinguish the two main market classes of cultivated chickpea—desi and kabuli. These data comprise a resource for chickpea improvement through molecular breeding and provide insights into both genome diversity and domestication.

• Potential and limits of exploitation of crop wild relatives for pea, lentil, and chickpea improvement (2020, background): “…kabuli type CDC Frontiers and desi type ICC4958) and the wild progenitor (C. reticulatum) have been sequenced (Bajaj et al., 2015; Gupta et al., 2016; Parween et al., 2015; Varshney et al., 2013), along with resequencing of 429 accessions of elite varieties and landraces (Varshney et al., 2019).”
• Fusarium Wilt Affecting Chickpea Crop (2017, background): “Chickpea, also called garbanzo bean or Bengal gram, is a self-pollinated, annual diploid (2n = 2x = 16) species [1] with a genome size of 738 Mb [2], While this size is slightly larger than that of the model legume, Medicago truncacula Gaertn.”
