All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley, during the past three decades, has been used considerably for the study of linkage groups and character inheritance. The commercial varieties are diploids, having seven pairs of chromosomes. Six linkage groups have been established. According to studies on interchange by Kramer et al. (1954), two linkage groups, formerly designated as III and VII, may be separate arms of the same chromosome. They are now generally considered as one linkage group.

Though more than two hundred characters have been investigated, less than sixty have been assigned relative positions on genetic maps. In many cases, selection for good characters is …
