An experiment was conducted to induce lodging tolerance for enhancing yield in dicoccum wheat varieties (Mudhol local and DDK- 1029) using plant growth regulators (CCC at 500 and 1500 ppm and Ethephon at 10, 20 and 30 ppm) during rabi seasons of 2009 and 2010 at Agricultural Research Station, Madhurkhandi, UAS Dharwad, Karnataka, India. The design of the experiment was randomized complete block design in factorial concept and replicated thrice. Among the two genotypes, the local variety ‘Mudhol local’ recorded significantly greater plant height (84.9 cm), stem length (77.3 cm), peduncle length (30.1 cm). Whereas, DDK-1029 produced significant higher spikelets per panicle (16.6), number of grains per panicle (32.9), panicle length (7.2 cm), panicle weight (85.2 g) and test weight (38.8 g). Ethephon at 30 ppm significantly reduced plant height (70.3 cm), stem length (60.6 cm) and yield (270 kg/ha) but increased tillers (390 m2) test weight (37.8 g), grain and straw yield (449 kg/ha) and HI (42.3%) which was closely followed by CCC at 1500 ppm. The interaction between growth regulator and genotypes showed that use of Ethephon at 30 ppm resulted in significantly higher grain yield (278 kg/ha), straw yield (396 kg/ha), panicle weight (92.0 g/ plant) and HI (47.5 %) in DDK- 1029 than in Mudhol local.
