Abstract : Sixty-eight varieties of mango were screened for occurrence of recurring flowering. Out of these, 28 exhibited problem of recurring flowering whereas the rest were free from this problem. The variety Alphonso and hybrid Neelum × Yermalgoa recorded the highest recurring flowering (20%). For control of recurring flowering in Alphonso mango, an experiment was conducted on 30-year-old trees during 1996-1997 and 1998-1999 in Maharashtra, India. GA3 50, 100, 150, 200 ppm were sprayed at 50% flowering, full bloom and at peanut stage of the Alphonso trees. All the concentrations of GA3, irrespective of the application time, significantly reduced the intensity of recurring flowering in both the years. GA3 at 50 to 100 ppm, sprayed at 50% flowering or at peanut stage, was an effective technique for controlling recurring flowering in Alphonso mango.
