Welcome to the PGSB barley genome database

Hordeum vulgare

Barley is an annual cereal grain from the Family of Poaceae and it has been cultivated for more than 7000 years. In former times barley grains were even used as currency by the Sumerian and Babylonian cultures. Nowadays barley is a major animal feed crop. It serves as an essential base for malting and brewing and to a lesser extend as component in bread and health food. Barley is widely adaptable to various climatic and soil conditions, because of its tolerance towards cold, drought, alkali, salinity. Regarding produced quantity and cultivated area barley ranks worldwide as number four after maize, rice and wheat.

The barley genome is diploid, contains 7 chromosomes and has a size of 5.1 Gb. The growing sequence data and subsequent analyses are a valuable resource for comparative cereal genomics and help plant breeders to develop new improved crop varieties.

A user training video about the use of genome resources for barley has been produced in the frame of the transPLANT project. You can watch it here: barley user training video.

This video shows the cooperation of Gatersleben (IPK) and Munich (PGSB) in barley research to cope with climate change.


The barley genome has been published online in nature (http://dx.doi.org/10.1038/nature11543) on Oct. 17, 2012, culminating years of work by the International Barley Sequencing Consortium (IBSC), a multi-national team of scientists from many countries. Read more from the international press release or from the HMGU press release in German language.

Access the genome sequence and annotation data as well as physical/genetic map+integration on the PGSB Barley FTP download page and through the search and browse interfaces of this PGSB PlantsDB barley instance (use navigation bar on the left).
