Genetic diversity and GWAS of agronomic traits using an ICARDA lentil (<i>Lens culinaris</i> Medik.) Reference Plus collection

Abstract Genotyping of lentil plant genetic resources holds the promise to increase identification and utilization useful diversity for crop improvement. The International Center Agriculture Research in Dry Areas (ICARDA) reference set plus collection 176 accessions was genotyped using genotyping-by-sequencing (GBS) 22,555 SNPs were identified. population structure investigated Bayesian analysis (STRUCTURE, k = 3) principal component analysis. two methods are concordance. Genome-wide association (GWAS) filtered SNP ICARDA historical phenotypic data discovered putative markers several agronomic traits including days first flower, seeds per pod, seed weight maturity. genomic developed utilized this study available research community interested exploring GWAS.
