Shoot formation and regeneration rates of calli derived from immature embryos of three spring wheat varieties were investigated to evaluate the influence on wheat regeneration of different concentrations of dicamba (0.5, 0.1 and 0.02 mg/l) in the regeneration medium. It was found that dicamba concentrations much lower (0.02 and 0.1 mg/l) than the levels reported previously (1 and 0.5 mg/l) induced significantly more shoots per callus in all three varieties, while the enhancement in regeneration rate was variety dependent. Overall, a dicamba concentration of 0.02 mg/l was more favourable for wheat regeneration.
