Hordeum chilense (2n = 14) computer-assisted Giemsa karyotypes

Abstract
The Giemsa karyotype of three accessions of Hordeum chilense Roem. and Schult were studied in detail. The idiograms were developed using a computer-assisted software program that contained the ability to straighten and measure chromosomes. Distinctive banding patterns were formed on each of the seven chromosome pairs, which in conjunction with length and arm ratio allowed the identification of each chromosome. Some differences in the banding patterns of the accessions were noted. Key words: Hordeum, chromosome banding.
