Due to the commercial importance of barley many hybridization studies have been prosecuted in an effort to produce superior economic strains. While the economic breeding is still important, at present there is considerable scientific interest int he inheritance of the characters and in the location of the genes in the different linkage groups.

Barley is rather favorable genetic material for such study. There is a great number of cultivated varieties and strains which differ widely in heritable characters. Barley can be grown under a wide range of climatic conditions and will produce rather large F2 families. The fact that it has only seven chromosomes makes linkage studies more feasible than in wheat or oats with their greater chromosome complements.

The characters studied in this paper are: black versus white glume color, long haired versus short haired rachilla, rough versus smooth awns, and branched versus unbranched style.
