Genotyping of lentil plant genetic resources holds the promise to increase the identification and utilization of genetic diversity for crop improvement. The ICARDA lentil reference set plus collection of 176 accessions was genotyped using genotyping-by-sequencing and 22,555 SNPs were identified after filtering for 50% missing data. The population structure was investigated using STRUCTURE (K=3) and principle component analysis. The two methods were in concordance. Genome wide association analysis (GWAS) using the filtered SNP set and ICARDA historical phenotypic data identified putative markers for several agronomic traits including days to first flower, seeds per pod, seed weight and days to maturity. This SNP genotype resource and seed of the accessions are available to the research community interested in exploring the ICARDA reference set plus collection using GWAS.
