Genetic Diversity of Global Faba Bean Germplasm Resources Based on the 130K TNGS Genotyping Platform

Novel germplasm resources are the key to crop breeding, with their genetic diversity and population structure analysis being highly significant for future faba bean breeding. We genotyped 410 global accessions using 130K targeted next-generation sequencing (TNGS) genotyping platform, resulting in a total of 38,111 high-quality SNP loci by high-standard filtering. found polymorphism information content (PIC) Nei’s gene were 0.0905–0.3750 0.0950–0.5000, averages 0.2471 0.3035, respectively. After evaluating PIC, on basis geographical origin (continent) structure-analysis-inferred subpopulations, we that from Asia (except China) Europe had rich diversity, while those winter sowing area China low. The divided into four subpopulations according clustering based (1972) distance neighbor-joining (NJ) method. However, same subpopulation contained materials different origins, thereby indicating flow or introgression occurred among accessions. Results NJ shared allele indicated three groups dissemination routes. results demonstrated relationships similar ecological environments geographic origins neighboring regions countries closer frequently within group, variation individuals was main source variation.
