Construction of a high-density genetic map: genotyping by sequencing (GBS) to map purple seed coat color (Psc) in hulless barley

Seed coat color is an important agronomic trait for the breeding and study of hulless barley as the colored varieties are more suitable for food processing compared to normal (yellow) varieties because they are rich in bioactive compounds and produce higher extraction pearling fractions. Yao et al. performed a genotyping-by-sequencing single-nucleotide polymorphism analysis of a doubled haploid mapping population to map the purple seed coat color genes (Psc).  Five structural candidate genes and one regulatory factor related to flavonoid or anthocyanin biosynthesis have been identified using a high-density genetic map of hulless barley. This study lays the foundation for map-based cloning of Psc by providing a valuable tool for studying marker-trait associations and its application to marker-assisted breeding of hulless barley.

Aims and scope

For almost a century, Hereditas has published original cutting-edge research and reviews. As the Official journal of the Mendelian Society of Lund, the journal welcomes research from across all areas of genetics and genomics. Topics of interest include human and medical genetics, animal and plant genetics, microbial genetics, agriculture and bioinformatics. Articles covering novel viral sequences or the use of new technology and software in genomic research are also welcomed.

Society information

The Mendelian Society of Lund was founded in 1910 and except for a short break during 1912-1916 has been active ever since. In 1920, the Society started to publish Hereditas, a scientific journal in genetics. In the post-genomic era, the scope of Hereditas has evolved to include any research on genomic analysis.
