Technical Abstract: The objective of this study is to investigate the variation in agronomic characters of barley plants derived from anther culture compared with the original cultivars, and select valuable mutants for barley improvement. Seed of three lines derived from anther culture of 'Andre', fifteen lines derived from 'Hector', ten lines from 'Morex', twenty-five lines from 'Moravian III' and nine lines from 'Otis' were planted along with selfed seeds derived from the original cultivars at two locations; one under irrigation at Aberdeen and one on dryland at Tetonia, Idaho in four replications at each location. The results showed that three lines derived from Andre were significantly different from the original cultivar in heading date, plant height, and seed weight. There was no significant difference in seed yield. Fifteen lines derived from Hector had heading dates ranging from 58-62 days, with at least five derived lines later than the cultivar and eight lines shorter than Hector. Seed weight was decreased in some lines and no difference was found in seed yield of Hector derived lines. Lines derived from Otis and Moravian III were similar to the original cultivars, with the exception of one line, line number 6, which was consistently later in heading, shorter, and higher yielding at both locations. Half of the derived lines from Morex were later than the cultivar, other characters were not significantly different. The patterns of variation depend on genotypes. These variations may be used to select desirable characters.
