Genetic diversity and population structure in Ethiopian mustard (Brassica carinata A. Braun) revealed by high-density DArTSeq SNP genotyping.

ABSTRACT:

Background

Ethiopian mustard (Brassica carinata (A) Braun) is a promising oilseed crop with the potential for sustainable biofuel and bio-industrial applications. Despite the presence of diverse germplasms in Ethiopia, their genetic diversity remains largely unexplored. This study evaluated the genetic diversity and population structure of 188 B. carinata genotypes using high-density Single Nucleotide Polymorphism (SNP) markers generated though DArTseq™ Genotyping-by-Sequencing (GBS). Of the 15,515 identified DArTSeq SNPs, 3,793 high-quality markers were retained and used to analyze the genetic diversity and population structure.

Results

The results from STRUCTURE, principal coordinate analysis (PCoA), and neighbor-joining tree analyses revealed two slightly distinct subpopu
