Bulbous barley
Hordeum bulbosum L.
Hordeum bulbosum, commonly known as bulbous barley, is a species native to southern Europe, northern Africa, the Middle East, and parts of Asia. It has been naturalized in North and South America, as well as Australia. Since 1970, it has been used in the Hordeum bulbosum Method to produce doubled haploid (DH) wheat and barley plants. This method involves crossing H. bulbosum with Triticum aestivum or Hordeum vulgare, followed by the removal of H. bulbosum chromosomes from the offspring. DH plants are valuable for breeding and scientific research. The species is also studied for its potential to provide genes for disease resistance and other beneficial traits in barley improvement.
Description
Hordeum bulbosum belongs to the genus Hordeum in the family Poaceae. It was first described by Linnaeus in 1756. The species is found in several regions, including Portugal, Belgium, France, the Netherlands, Great Britain, Ukraine, Hungary, and the United States. It is used in plant breeding to generate doubled haploid plants through a specialized method. These plants are important for developing new varieties of wheat and barley. Research is ongoing to explore the genetic potential of H. bulbosum for enhancing barley crops with traits such as disease resistance.
