"Background: Genetic improvement of pearl millet is lagging behind most of the major crops. Development of\r\ngenomic resources is expected to expedite breeding for improved agronomic traits, stress tolerance, yield, and\r\nnutritional quality. Genotyping a breeding population with high throughput markers enables exploration of genetic\r\ndiversity, population structure, and linkage disequilibrium (LD) which are important preludes for marker-trait\r\nassociation studies and application of genomic-assisted breeding.\r\nResults: Genotyping-by-sequencing (GBS) libraries of 309 inbred lines derived from landraces and improved\r\nvarieties from Africa and India generated 54,770 high quality single nucleotide polymorphism (SNP) markers. On\r\naverage one SNP per 29 Kb was mapped in the reference genome, with the telomeric regions more densely\r\nmapped than the pericentromeric regions of the chromosomes. Population structure analysis using 30,208 SNPs\r\nevenly distributed in the genome divided 309 accessions into five subpopulations with different levels of admixture.\r\nPairwise genetic distance (GD) between accessions varied from 0.09 to 0.33 with the average distance of 0.28. Rapid\r\nLD decay implied low tendency of markers inherited together. Genetic differentiation estimates were the highest\r\nbetween subgroups 4 and 5, and the lowest between subgroups 1 and 2.\r\nConclusions: Population genomic analysis of pearl millet inbred lines derived from diverse geographic and\r\nagroecological features identified five subgroups mostly following pedigree differences with different levels of\r\nadmixture. It also revealed the prevalence of high genetic diversity in pearl millet, which is very useful in defining\r\nheterotic groups for hybrid breeding, trait mapping, and holds promise for improving pearl millet for yield and\r\nnutritional quality. The short LD decay observed suggests an absence of persistent haplotype blocks in pearl millet. The\r\ndiverse genetic background of these lines and their low LD make this set of germplasm useful for traits mapping."^^ . "2020-07" . . . "21" . "1" . . "BMC"^^ . . . "BMC Genomics (TSI)"^^ . . .
