A chickpea genetic variation map based on the sequencing of 3,366 genomes.

ABSTRACT: Zero hunger and good health could be realized by 2030 through effective conservation, characterization and utilization of germplasm resources¹. So far, few chickpea (Cicer arietinum) germplasm accessions have been characterized at the genome sequence level². Here we present a detailed map of variation in 3,171 cultivated and 195 wild accessions to provide publicly available resources for chickpea genomics research and breeding. We constructed a chickpea pan-genome to describe genomic diversity across cultivated chickpea and its wild progenitor accessions. A divergence tree using genes present in around 80% of individuals in one species allowed us to estimate the divergence of Cicer over the last 21 million years. Our analysis found chromosomal segments and genes that
