The Vavilov seed bank contains numerous landraces collected nearly hundred years ago, before intensive breeding of most crops, and thus is a potential reservoir of historic crop adaptations. Here we analyze the genomes of 407 of Vavilov\’s original landraces, sampled from major historic centers of chickpea cultivation and secondary diversification. We performed GWAS to find associations between VIR’s chickpea accessions and phenotypic data obtained in Kuban experimental station of VIR in 2017 under infectious conditions. To find out the effects of infectious conditions on phenotypic traits, the data was subjected to AMMI and GGE biplot analyses.
