Abstract : Scions from three varieties were exposed to gamma rays, ethyl methanesulphonate (EMS) and N-nitroso-N-methylurea (NMU) and grafted onto one-year-old seedlings. The LD50 values for gamma irradiation of Neelum, Dashehari and Mallika (Neelum X Dashehari) were 3.9, 2.9 and 2.4 krad, respectively. Primary effects of physical and chemical mutagens were similar. Repeated cutting back of treated plants of Dashehari and Mallika for several seasons resulted in stabilization of certain vegetative characters. A few plants appeared promising for dwarfness and in some fruit quality was improved.
