Interpretive Summary:

Technical Abstract: Genes for short stature or semidwarfness in barley have been used in many breeding programs to reduce lodging and increase seed yield. However, data obtained from agronomic studies of semidwarf derived lines are still inconclusive. This study was conducted to compare agronomic characteristics of a normal height parent to various semidwarf derived lines planted under irrigation and on dryland. Seven barley genetic stocks derived from the cultivar Bowman backcrossed two to seven times with various semidwarf mutants were planted in replicated plots for three years at two locations in Idaho, under irrigation at Aberdeen and on dryland at Tetonia. The following agronomic characteristics were recorded: heading date, plant height, seed weight, and seed yield. Under irrigation, several semidwarf lines were equal or superior to Bowman in seed weight and seed yield. At least one semidwarf line was later than Bowman in heading. On dryland, none of the semidwarf lines were comparable to Bowman in seed weight and seed yield. Semidwarf genes, therefore, could be useful for development of cultivars adapted to irrigated environments.
