Investigations were carried out at the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, during 2003-2005 to work out radiosensitivity of five varieties of amla (Emblica officinalis Gaertn.) exposed to different doses of gamma rays. Scions of five amla varieties, viz., BSR-1, Kanchan, Krishna, NA-7 and Chakaiya, were irradiated with different doses (1.0 to 5.0 kR) and these were grafted on to ischolar_mainstocks. Based on the sensitivity study, LD50 for 100% survival ranged from 1.0 to 2.0 kR for all the five varieties. All the amla varieties could survive upto 10-20% at lower doses (upto 2.5 kR).
