Gibberellin (GA) relationships in an induced dwarf mutant of barley, brachytic (gene symbol br2) were investigated. The dwarf mutant was suggested to have genetic blockade at the site of conversion from a "pool GA" (presumably GA19) to an "active GA" (presumably GA3) in the pathway of GA biosynthesis. An application of (2-chloroethyl) trimethylammonium chloride (CCC), an inhibitor of GA biosynthesis, to the corresponding normal form (cv. Svanhals) reduced the growth and that of GA3 to the dwarf mutant restored the reduced growth. In all possible hybrid combinations, among 3 dwarf genes, uz, br and br2, all F1 hybrids showed tall normal plant height, thus the site of genetic blockade, if any, may be different one another within these 3 dwarf genes.
